In preparation for this fall I decided to invest in a new pair of shoes that would keep my feet happy and dry even during wet conditions.
For this I ventured into town and visited sport and outdoor shops to try on different brands and types.. but I was unable to find anything that felt good on my feet.
In the last store I saw a pair of ON Cloudventure in the wrong size and it was the last pair.. They felt different compared to the other shoes I had looked at. and they managed to poke my interest enough to make me spend the evening researching them.
So, after an evening of reading reviews I decided to order a pair directly from ON.
I used their size guide, knowing that Salomon size 44 works for me, the guide suggested 45. I chose mustard yellow as he color and clicked buy. Felt safe with the 30 day return policy.
Delivery was to the door by UPS on Friday lunch, was estimated for Wednesday the week after. A pleasant surprise and the weekend promised rain so even better with a pair of new waterproof shoes.
And for honesty, I'm a sucker for the name 'Cloudventure', just makes me want to try them! : )
First impression
Inner side view and top view of ON Cloudventure Waterproof Mustard. I like how they say 'No excuses' inside the shoes!
Bottom sole view and top view of ON Cloudventure Waterproof Mustard.
Just putting them on right when they arrived and I knew that I had made the correct choice. Compared to other shoes that I tried during this search, these felt comfortable from the start, very light and easy to walk in. At least indoors.
First time outdoors testing was a 3 km walk in dry conditions on an exercise track with topping of wooden chips. A lot of up and down gradients. And no problems here either, no hint of blisters or anything like that. Just felt good to walk in. Even though I have problems with my right foot from my chemotherapy with numbness etc. these felt OK. Other shoes can get a 'floating' feeling on that foot.
Three pine cones lodged into the sole of ON Cloudventure Waterproof. One of our cats, Pixel, in the background.
When I came home I noticed that three pine cones had lodged them into the sole. Need to check if this happens often or if they clean out by themselves. I did not notice anything during my walk but that could have been thanks to my numb foot as well..
Waterproof or not?
I've done one walk in the forest after some heavy raining and I tried to walk through all the puddles, wet grass and wander around without any trail to walk on and to my surprise, my feet kept dry. So in my book, good enough for me.
Heel slippage
This is a problem that I have with all my shoes. So no surprise here, it is not much and can be helped with lock lacing. Kind of takes away the problem.

I've been quite happy with the original Schwalbe Marathon Mondial 700 x 40c tires that came with my Kona Sutra. But last winter when I changed wheels to Mavic Allroads that were nicely tubeless ready and now that my wife bought a mountain bike I decided to go for new tires for a more comfy ride on gravel and singletrack.
Basically the same style as Schwalbe Marathon Mondial but tubeless. I.e. touring tire, and not what I am looking for at the moment. But keeping in mind for when my Marathons wear out! But they need to come back with the slate sidewall, they look really nice compared to the all black ones.
Larger volume than what I have today, but not quite at the WTB levels. Unsure if my fenders will fit it. Has puncture resistance built it, and cheaper then WTB tires...
I decided to go with Panaracer Gravel Kings. Worst case is that I have to remove my fenders, so be it. But what tipped me over was the extra puncture resistance that was missing on the WTB tires.
Installation
After some trouble with DHL delivery that took quite longer then expected (wiggle returned the delivery fee as DHL hadn't picked up the parcel until after they should have been delivered... at least they try to be customer friendly)
First time that I install tubeless tires, I've used Schwalbe Ones on my racer but with inner tubes and I know that they were a pain to get on the rims. So my plan for these was:
Mavic Allroads are already taped from the factory, so no need to work on that. Just double check that it is smooth and in place.
Install the valve that was included with the wheels. Turns out it did not have removable inner core. But no worries.
Put on the tire, use soap water on the last bit to get it over the rim.
Pump it up so that the bead sets
Open up one side and pour in sealant, I used Muc-Off No Puncture Hassle 140ml Kit. 5 cups, so 2*140ml kits and some was left over.
Rotate the sealant away from the opening so that it doesn't pour out.
Close up. Rotate it again and make sure that the sealant goes everywhere.
Pump up again so that it pops in place and then to your desired pressure.
First wheel, no problems.
Second wheel... A lot of problems but turned out that my pump broke so that was one clue as I tried the inner tube trick to get the bead to set the first time and the innertube did not inflate either.
So a new pump the next day, inner tube broke down. Tried with another inner tube, the valve on that one broke down. And then back to original plan with the tubeless setup and new pump and it just worked.
So note to self, if pump breaks down go back to original plan.
Fender fit Kona Sutra (2019) original fender
The 700x43C tyres fit just and just in the original Kona Sutra fenders. I love to have stylish fenders on my bike even when running over rough terrain, so this made me genuinely happy!
First impressions
First ride was 27 km exploring some new roads and trails. Managed to not record any video as my SD card was in the computer at home. Noticed that after a while...
Paved road impression
Rolled quite good, no noticeable difference to the Marathons. The road sound was OK, nothing too loud even though the Gravel Kings are quite a lot nobblier. Liked.
Gravel road impression
Packed dirt road with gravel on top
What I noticed directly compared to the Schwalbe Marathon Mondial was that small stones did not feel as much, the tires just swallowed them. Even as I ran them on 3 bar (~43 PSI).
First time cornering was a little bit of an unknown so I took it easy as the stones tend to roll on my old tires, but no issues here, felt that I had grip all the way and in the next corner I had more confidence and was able to keep a higher pace.
Larger sized gravel sections
A little bit bumpier but that was to be expected. But still rolled nicely over them.
Farm roads (2 track etc.)
My favorite type of roads as these tend to take you to places less visited and the real nice experiences. These are also not maintained that well.
No issues here, rolled nicely over the grass sections and had firm grip all the way. Cornering was nice as well.
The mud sections that I came across were quite simple and I just rolled through them, nothing too deep or long.
Wet sandy exercise track with roots and stones on climbs. This was a traction test, and I must say that the Gravel Kings were the right tyres that make it possible for me to get up. Tubeless with lesser pressure made many of the roots and rocks disappear and the nobbles held the grip even in wet sand. Wide enough to not dig too deep into the sand. Need to test same place on a dry day.
Advanced single track
I came by a quite advanced single track that I hadn't ridden before with a lot of gnarly roots and stones. But no issues here, the weather was quite dry so probably helped quite a lot. Had wheel spin once as I stopped on a uphill gradient and tried to restart, quite sandy. Always nice to know that the bike and tires will handle it even though I probably will not try that section again, a little too advanced for my taste these days.

Göta Kanal, Sweden. From Jonsboda to Vassbacken and then to Tåtorp.
Watch out for ducks outside of Vassbacken and a Heron before arriving in Tåtorp.
On my Kona Sutra 2019 with SRAM Eagle GX
The 2.5 km track in Ullervad is a nice exercise track with a lot of up and downhill gradients that get your hearth pumping a little extra, even during a walk.
The lights start at the parking lot on the other side of road 201 and you do not need to cross the road as there is a tunnel.

The good
Lights, really good light setup all around the track.
When I was in the hospital in January 2020 after they told me that my tumor was inoperable I decided to start vloging my experiences. But I did not have any camera and pretty soon I decided that my cellphone camera just was not cutting it. It always went to refocus mode when trying to film even the smallest clip.
So, for some time I've wanted an action camera so I thought this is the time to buy one.
I ended up buying the GoPro Hero8 Black and I've used it for 6 weeks both on my adventure bike, when walking, when running, when filming indoor talking head stuff and filming our cats. So I thought it was time to summarize a review of what I like and what I do not like about the camera.
Battery time
Ok, this is my first action camera and the first time I've used a dedicated video camera in over 15 years? Honestly, I thought that the batteries would last longer, i.e. active recording time.
That was my first reaction... Turns out I did not need to worry. But just in case, always bring an extra. I haven't checked exactly but it drains about half a battery on my walks if I record the whole thing so a total of around one hour of battery when filming 1080p/60fps. I always carry a backup just to be sure as I tend to forget to recharge them when I get home.
External battery charger is on my buy list but for the moment I just plug the USB-C into the camera and charge them one by one
Focus
It just does it. Never had 'refocusing' blur on the GoPro.
Audio quality
The internal microphone picks up pretty much every sound around you. But I don't know how else they would have done it. But not good enough for me, so I ended up buying an external microphone. At first I thought about the GoPro media module that would allow for recording directly to the camera. After some more research I decided against that approach due to the media module killing the weather resistance of the GoPro Hero 8 as it requires the battery flap to be removed. And I do a lot of walk and talk stuff outside, even when the weather goes ugly. So an external microphone it was for me. It records to my mobile phone and I can sync the sound later when editing the video.
Video quality
1080p/60fps
So far I've recorded everything in 1080p/60fps.
What I like is how good the stabilization works. As I wrote above, I do a lot of walk and talk shots with the GoPro Shorty and the stabilization just works. I even found that it could handle running parts quite good.
Video example of Walking / Running with stabilization on. Using a GoPro Shorty to hold the camera.
Stabilization when mounted directly to my bike is smooth, can't see and extra movement. Almost a little boring.
Video example of Cycling with stabilization on.
Video example of indoor with bad lighting on a tripod
4K/60fps
As my computer does not have a 4K display and some render times are over 2 hours today for 1080p I've opted out from using 4K as for now.
But it is good to know that the camera supports it when the day comes for a new computer : )
Buttons
It has 2.
It should not be so hard.... Right?
But the power button also changes between record film, take a photo or do a timelapse. And if you are not paying very close attention you might just screw that up.
After failing totally with this once I figured that the start/stop filming button also starts powers the camera on in the last mode it had so it feels a lot safer to use. And also pay attention to the icon on the front screen, it gives a hint of what mode you are recording in.
But yeah, one 30 minute video lost to this and I started wondering if this is a good design or not. It could be a little harder to change the mode. I mean, it is something that you would want to do deliberately, not by accident. Like switching from 1080p to 4K, you use the touch screen and it is no hassle. Let the power button be on/off and recording button be start/stop. Can't stand double purpose buttons.
GoPro Mounts and Accessories
To get something more out of the GoPro, you will need mounts
The GoPro Shorty
GoPro Hero8 Black on a GoPro Shorty standing on a table
This is the mount that I use for pretty much everything.. When filming my VLOG entries at home I just expand it to its longest and put it on the table and start recording. Works like a charm.
I have it with me when I go on walks
I ended up changing the included screw to a standard GoPro thumb screw. The original was just too hard to get to.
The good:
Super small, fits in my jacket pocket with the camera on
The bad:
Does not have a quick release system. I.e. thumb screw on and off
This is the second piece of original GoPro accessories that I own. I mainly use it for cycling videos as it shows a more bike inclusive perspective than the QuadLock Pro mount at at the front of the bike does.
The good:
Sturdy
Comfortable and can be adjusted to fit tight
Quick release system
The bad:
Have not found anything that I don't like about it yet.
GoPro Hero8 Black mounted to the QUadLock Pro Front Mount
This is on my adventure bike as I use my phone for maps and quick access to a camera. The nifty thing here is that it has a mount for the GoPro on the underside. So just use the thumbscrew and fasten the camera and you get a nice view forward from the front of your bike.
As said before, this can become quite boring if you only film that view but a nice addition to other angles.
The good:
Simple mount for both your phone and GoPro
The bad:
Does not have a quick release system. I.e. thumb screw on and off

The 2.5 km track in Timmersdala is signed with a diagonal blue box around the track. At some points where there were crossings from other tracks it was a little hard to follow what way to go.
This track is very much gradient heavy with a max of 23% according to my Strava track profile. Don't know how accurate it is but sounds about right after the walk. So a pulse heavy session with a lot of ups and downs.
Walkthrough
The good
Lights, really good light setup all around the track.
There were some benches and tables at the start.
Clear sign at the start describing the track
Lights to and from the parking
The bad
The signs around the track were a little lacking, some additional signs with arrows would have been nice. No distance signs around the track.
A short but sweet track in Moholm, nicely isolated from any major road. Only sound is from the forest or the train tracks a bit away.
The track is mostly flat.

The bad
Short
The lack of signs, just a half-way point sign would have been nice.
The trail goes counter clockwise. The first part is pretty flat, it comes quite close to the road at some parts so you can see and hear the cars. When the track turns east it starts to slowly go downhill and when it turns back west we have an uphill segment with an average gradient of 5% (according to Strava).
Walkthrough
The good
Lights, really good light setup all around the track.
Outdoor gym at the start area
A lot of places to sit around the track.
Clear signs for short-cuts and other information
The bad
Partly very close to road 26. At least the first part, a lot of car noises.
The parking space was a little small and had a lot of large holes in it. Luckily I have a larger car, but I think that it might be a problem for smaller cars.
No lights on the dirt road to and from the parking lot. Actually gets pretty dark here.
They found something blocking my bile duct that they think is cancer. After battling acute pancreatitis in the autumn I was to undergo a Whipple surgery in January, during which they found that they can't do that. As the tumor i too locally advanced, meaning that it has grown in to stuff in my case one of the main veins and arteries going to the liver.
So I am back on chemotherapy after a year without. I decided to start a VLOG on YouTube about it if you are interested in following me on the journey. If not, up to you. : )
How it started this time
Last June (2019) I got severe stomach ache and had to go to the ER one day before a planned adventure biking trip. At first they thought that it was bile stones, but nothing showed on CT-scans. On MRI-scan where they did not see any stones but they saw that the bile duct was blocked by something.
Potato quality photo of MRI showing part of bile duct is blocked by unknown mass.Should be white between the red lines.
At this point the talk starts about cancer. Again. In 2018 I was operated twice for bile duct cancer and they ended up removing half of my liver. Followed by a six month chemotherapy with pills. Doctors at my local hospital told me that there would be another surgery to remove this unknown mass and that they would coordinate with the pancreas team in Gothenburg, Sahlgrenska.
Hence began the waiting game.
23rd of June 2019. Still weighing in at 101. 2.5 kg down since ER.
During the coming weeks I did some more MRI-scans as the Pancreas team wanted some more pictures I guess. On July 12th I received the call that I was scheduled for a Whipple surgery and that I should go to Gothenburg and meet with the doctors there. At this point my eyes and skin have started showing a little yellow tint.
14th of July 2019, 98.5 kg. Continuing downward.
We meet with the doctors the coming week and they say that it is a 6 week queue, they also describe the surgery and that it is a major one that will rewire some of my internal organs. At this point it is evident that I am yellow. And I am itching all over my body.
I receive a date for mid August for the Whipple operation.
Acute Pancreatitis
31st of July 2019, unknown weight, probably less then before.
On the 31st of July I had to call the doctors and say that I needed to come in. I couldn't cope with the itching and I was turning really yellow now and also I felt that my body really wasn't picking up any energy from food anymore. They called back and told me to come in, I was scheduled for a surgery the next day for opening up my bile duct.
At this point you might wonder why didn't they do that from the beginning. Open up the bile duct that was blocked with the help of a plastic pipe. That's what I wondered. During the next few days the yellow vanished and itching stopped and everything got better. Until it didn't.
It turns out that there is a ~5% risk of getting acute pancreatitis with this procedure. And that is what I got.
16th of August 2019, 98 kg
At 10th of August I was up to 106 kg. But this time with fluid building up. They fixed that with diuretic medicine to get rid of the excess fluids. And on Wednesday 21st I weigh in at 93 kg. They cut my antibiotics and sent me home (twice that week).
23rd of August, 93 kg. Happy to be home
On 24th I got back in ER and I was in a really bad shape. It hurt everywhere and I received a ton of painkillers.
28th of August 2019, CRP at 338. This is quite high....
The next week I do not remember anything of, I received painkillers intravenously and deteriorated.
1st of September 2019, High fever, 105 kg
On 2nd of September I was sent to the Intensive Care Unit due to signs of bleeding in the cyst that had formed around my pancreas. I received the first painkiller that actually helped in the form of a spinal anesthesia. I weighed 109 kg
The next evening, on the 3rd after a month at the hospital. I was sent to Gothenburg with ambulance for specialist care.
4th of September, 2019. High on medicine and receiving blood. I did not log any weight during September.
During September I don't remember much, other then the low fluid intake scheme that was in place during the first week. I.e. was not allowed to drink more then 500 ml per day. That was hell.
10th of September 2019. Upper body does not show any extra weight, more like less weight. But stomach and legs were just huge. Regret that I don't have any photo of my legs.
After a couple of weeks in Gothenburg they put in a pipe from my stomach to the cyst around my pancreas to start shrinking it. And I think that was the turning point of sorts, even though I continued to have fevers for a while everyday and fever chills. Longest was 3 hours of uncontrollable fever chills.
22nd of September, another fever night with no sleep
Turns out I didn't record any weight changes during October either. Must have had other things on my mind. But I think I peaked out at 117.5 kg. Last weight without extra fluids was 83 kg. So 24.5 kg of extra fluids in my body. My legs were like tree-trunks and I had a really hard time walking.
When they finally managed to get me to loose the fluids, (daily process that really went on from day one in Gothenburg). I landed at 80 kg. So 37.5 kg loss from the max weight during this time. I have flames as proof.
2nd of October, got help with washing my hair.
5th of October, first time with a chair bike.
First weeks of October I started to be able to walk a little longer, i.e. not just the corridor outside my room but to other parts of the hospital. Just leaving the surgical department was nice as I've been there for so long at this point. But always with a nurse as damn, can't trust my legs.
October was up and down, when bloods started going the correct way my body decided it was time to go on strike. During September all the lab values were skyrocketing but my body was like, I'm fine.
A lot of nausea, vomiting and finally unable both eat and drink. In the end I think that it was my brain, it wanted to get away. The only medicine that helped against the nausea was a pill against worrying. I.e. one that calmed my brain. When that week was over, or was it 2? Can't remember, they sent me back to my local hospital.
25th of October, feeling OK. Hoping to get closer to home in the next week.
2 months in Gothenburg.
I spent the better part of November at the hospital in Skövde. At the end I only needed to go in for antibiotics (that I've been on since August) and was able to sleep at home. That was a huge relief. Three months, three and a half month in a hospital really takes its toll mentally.
7th of November, up and walking with no help
In the end of November they removed the pipe from my stomach to the cyst that had emptied itself successfully.
19th of November, home at last, 82 kg
I was switched over to antibiotics in pill form but when they ended it took two days until I was back at the ER. Totally crashing.
A few day at the hospital again and back home with new antibiotic pills.
After they ended it took a week, the week before Christmas until I crashed again. The doctors said that I was to be on antibiotics until the Whipple surgery was done, so I was allowed home during the day on Christmas, but New Years Eve I spent at the hospital, if I remember correctly I switched rooms when the bell rang due to faulty ventilation.
The Whipple Surgery
On 8th of January 2020 I they did the Whipple surgery in Gothenburg. Or, well they started to do it. But turns out that they were not able to remove the tumor. And thus did not perform the Whipple at all.
Evidently, if they would have tried to forcibly remove it the risk would have been very high that they could have nicked one of the main arteries going into the liver and I would have died there and then. Fun stuff.
I was a little suspicious when I arrived at Post-Op hours before estimated but as I was high on medicine I didn't pay that much of attention.
The next day, still at Post-Op, the operator that performed the surgery came to visit and told me the news. They were not able to remove it and they could not do anything more surgically.
When I got back to my room he visited again, this time when my wife and sister were present. And pretty much told us that better plan for the worst, there is a miracle chance that it might be operable after a chemo treatment but that the chances are close to none. So basically, I will die of this.
They had also switched the plastic pipe to a metal one in my bile duct, hopefully removing the need for antibiotics as the doctors thought that the plastic pipe might be the source.
12th of January, 2020. After failed Whipple surgery
I was sent back to Skövde for recovery and to start chemotherapy.
23rd of January 2020. New glasses
In the weeks to come after the surgery not much happened, I got the flu, my oncology doctor got the flu. Time passed, but then again I could not start the chemo before my surgical wound was healed so I guess it did not matter.
Chemotherapy
This is where we are now. Started chemo a week ago (7th of February) and received my second treatment yesterday.
My oncology doctor says that there is a real chance that chemotherapy should work. He was a little baffled at how the operating surgeon had presented the chances. So that is what I will focus on from here on. That there is a chance, and 3 months of chemo will be pain but At least then we know if it has effect or not.
At this point I've also started a VLOG, if you are interested in following it please head over to youtube! I don't know if I will write more about it on this blog though so the VLOG is where I will update on that subject. And the occasional Instagram photo of course.
One thing that has been a thorn in the side of my Kona Sutra experience was the front derailleur. When I had a mountain bike I converted it to a single narrow wide chainring in the front and got rid of the front derailleur completely. It changed my whole mountain biking experience to something more positive, not having to think about when to go to the small chainring, doing that in the wrong section could prevent you from going back to the large for a long time. And the occasional involuntary downshifts that happened were not fun either.
So, after riding quite a bit of roads and trails I decided to upgrade my Kona Sutra to a single chainring system this winter.

Gears
Before anyone starts commenting on x3 vs x1 setups, I know that this is not ideal for everyone. A lot of touring people seem to favor the 3 chainring design and I am sure that it has its place. Everyone should opt for the bike configuration that they think is the best for their needs, no need to bash others. Now that that is out of the way, lets start to look at the gears of the two drivetrains in question here.
The 2020 Kona Sutra Ltd comes equipped with SRAM Rival x1 drivetrain, the reason I did not want to go that way was because it is only 11 speed and I wanted the 12 speed SRAM Eagle as it is on the market.

A visual comparison of the gears between the Kona Sutra original setup and the SRAM Eagle (Click on the picture for a bigger version) (tool used: ritzelrechner.de)
What I am gaining
Even lower climbing gear then the 26/11 on the original setup
What I am loosing:
The going fast gears, but honestly I seldom use those and even less when the bike is fully packed. If it is a downhill section, I tend to rest when the speed starts to get above 30 km/h, so that I can tackle the next uphill that is bound to show up soon.
Longer steps between gears
To clarify the last bullet of longer steps between gears, let's look at another picture to visualize the difference.
Top line, the original 9 speed casette on the Kona Sutra, lower line is the SRAM Eagle cassette (Click on the picture for a bigger version) (tool used: ritzelrechner.de)
The 9 speed 11-34 cassette is able to put the gears in a tighter space (smaller steps between gears) then the SRAM Eagle 10-50 cassette is able to. From what I understand, this seems to be one of the key issues that people have with the current SRAM Eagle.
For my uses, I think that I should be able to live with the difference. The biggest steps seem to be when going to the lowest and highest gear, normal riding is usually done somewhere in the mid-range and the cogs there seem to be better packed. Or, I just have to live with the pain until I get strong enough to handle it.
To convert the Kona Sutra to SRAM Eagle I ended up buying a lot of stuff, and it got a tiny bit more expensive then I originally thought it would be...
I went with the SRAM GX version of the Eagle drivetrain. There was a cheaper one, the NX, but it went from 11-50 and I read some review stating that the cassette was not that high quality, so I got scared and went for the GX that seems to have gotten better reviews. The X01 and XX1 are out of my budget.
As I got the DUB groupset, I also needed a new DUB bottom bracket that fit into the BSA threading of the frame. And a the SRAM Eagle is originally built for mountain biking, I needed to find bar-end shifters that were compatible, and luckily there are, from microSHIFT. They also seem to support other obscure new 12 speed drivetrains like the one from Shimano.
And as I threw the front derailleur in the trash, I needed to plug the bar-end on the left side. I have some nice plugs on my racer with allen-key tightening so I went with similar for the new setup. Works like a charm on the racer and never drops out.
Oh, and don't forget to buy new handlebar tape as you need to remove the old one to get to the cables for the bar-end shifters.
That's all, right? Wrong!
Turns out to be able to fit that huge 10-50 cassette on the back-wheel you need a SRAM XD Freewheel Body. And, as the hubs that are originally on the Kona Sutra are of a brand called Formula, it is almost impossible to find the correct one (if there exists one).
So I ended up buying a new wheelset, something that I thought of doing ever since the 3 day escape we did in May as the front wheel wobbled and it still does even after my local bike-shop tried to fix it and after that I tried to true but the wobbling persisted. All bikes in that price segment ship with shitty wheels, just have to live with it : )
So..
I think the NX would have fitted the Shimano freewheel hub, but well.... I was doing this so I did not want to change to the NX just for this. In the end I would have bought new wheels anyway, it's just the way I tick, I like to upgrade my bikes and enjoy that process almost as much as I enjoy riding them.
Removal of old parts
In this section I'll just go through the things that stopped me for a bit.
Chain
Top: The KMC missing link in its unlocked state. Bottom: My master link tool with dual function, an be used for both unlocking and locking of master links.
To remove the chain, use a master link tool and just open the missing link. I did not have a tool when
I started out so I tried to break the chain but my chain-breaker did not manage to do it.
Had to drive into town and buy a master link tool and the link just opened in less then a second. Well worth the 15€.
Bar-end shifters
For removal of the bar-end shifters:
Put the lever in its down position
Remove the flat-head screw and its nut (on the other side)
Remove the lever
Use an 6mm hex (allen-) key and turn it clockwise to unmount the shifter
Pedals
Pedals usually require a bit of violence to come of the cranks. I use a rubber hammer.
Bottom bracket
Ah, this one beat me. The drive (right) side was quite easy to remove with the help of a rubber hammer on the bottom bracket removal tool. But the left side did not move even with rubber hammer force applied.
Bottom bracket removal kit. A bottom bracket tool and an extension bar
What finally did the trick was.
Apply lubricant that is able to penetrate the threading, I used WD40.
Wait, I went and ate dinner and watched a movie.. 3 hours maybe
Use a cheater bar, or something to extend the tool. I used a long metal pipe. The handle of your tool must be able to fit inside of the pipe.
Place the frame on the floor and stand on it, use one hand to hold the tool in place and the other to apply force on the cheater bar.
Finally the bottom bracket moved
Handlebar tape
Make sure to document where the shifter cable goes through the old handlebar tape as you will have to make sure that it will come through at the same place after you have put in the new 12 speed shifter.
So fingers crossed all this new stuff works together.
Wheels
Ah damn. The body I got was the XD-Race and SRAM Eagle is XD compatible. Luckily the body came with a spacer that made it XD compatible.
Changing the body was a pain, looked through a lot of youtube videos where they just popped the body out. Turns out that's the way to do it, I just was too weak to do it the first 30 times. Just fingers and a long pull on the whole body and it will pop out from the Mavic 360 freehub.
Using torque wrench to tighten the screws that hold the disc on the wheel. In my case it said 10Nm per screw. Make sure that you read you manual for the wheel you use
Switching the old discs from the old wheel-set to the new one was no problem, just unscrew and screw it in place again.
Cassette
Tightening the SRAM Eagle GX Cassette with a normal cassette tool. (Same that I use for Shimano)
No problems here either, once the freehub body was changed and the spacer was popped in there, just sliding the new SRAM Eagle cassette in place was no issue at all.
My torque wrench only goes to 24 Nm, so I had to just tighten it by feel. I.e. as hard as I could get it. This is the same tool I use for Shimano cassettes, so at least they are compatible on that part.

Bottom bracket (BB) and crankset
SRAM DUB BSA Compatible Bottom Bracket Tool
This turned out to be a problem, none of my bottom bracket tools fit the new DUB bracket. So I need to drive and visit my local bike shop and see if they have the right tool for sale. They didn't, but they ordered one for me (20€), one for their shop and a couple for sale. Evidently threaded DUB bottom brackets are quite rare.
Almost completely installed SRAM Eagle on a Kona Sutra, only thing left is to install the wire to the rear derailleur.
This was quite easy. Just bolt it in place just like the old Shimano mech was there.
After that, install the chain. You will need a chain breaker. Be sure to look at MTB and Road Cassette and Chains PDF linked below to find out how to measure the chain correctly before you use the chain breaker.
When you have the correct length, install it on the 10 cog on the cassette and through the rear derailleur and install the power lock.
At this point it is good to measure the length of the chain so that you can check it for wear later. 11 of links on my chain was 132 mm. SRAM recommends that you change the chain when it is 0.8% elongated. In my case 1 mm. If in doubt use a longer bit of chain to measure.
For adjusting the rear derailleur, I'll just link to Park Tools, they have a nice guide on how to do it. Be sure to use the SRAM Eagle mounting guide that was in the nice SRAM Eagle box, the red plastic one to make sure that the distance is correct between the cassette and the first guide pulley in the derailleur.
Bar end shifter
The new microSHIFT bar end shifter was pretty much identical to the old Shimano ones, meaning that you just put it in the bar end and tighten it by counter-clockwise with an hex key.
Wrapping new bar tape
Before you start, make sure that the cable housings are taped to the the bars, I use electric tape. The original tape was not that good and I ended up redoing it all.
After that, just wrap the tape. Begin at the bar-ends and work your way inward.
Make sure you check if you bar end tape has a preferred wrapping direction, I didn't and did it the wrong way. Total failure and as I was too confident I didn't test without removing the plastic cover of the glue.. Long story short, had to order another roll to cover that mistake.
I usually tape the start and end of the bar-tape with electric tape just to make sure that it doesn't start to unravel.
That's it!
There were quite a lot of stuff to install but I think I've covered the bits that stopped me in some way or the other. I.e. bits that I did not find straight forward.
Weight
One of my goals with this was also to get rid of some weight. With all the stuff on the bike, lock, surly front rack, pedals etc the bike weighted in on excessive 16 kg before doing the upgrade. Only the front wheel with tyre was 1.9 kg.
So, with all other stuff still on the bike, the number to beat with the new components listed above is 16 kg.
Total weight before upgrade: 16 kg
Total weight after upgrade: 14.9 kg
Total change: 1.1 kg
Front wheel with tyre before upgrade: 1.9 kg
Front wheel with tyre after upgrade: 1.6 kg
Front wheel change: 0.3 kg
I guess the majority of the weight loss comes from the new wheel-set.
Test ride
As I am not 100% fit at the moment due to a longer hospital stay this fall and failed Whipple surgery 3 weeks ago that still bugs me, I will not do any long test ride at this point. I mean, I've lost all my muscles and it will be a long process to get back in shape.
But, a ride around the block should be possible and encouraged by my doctor so that is what I'll do.
In total 4 km flat, 1.5 km on asphalt and the rest on dirt roads.
The bike handles very nice, pedaling is smooth and switching gear works good.
Can't really comment on the bike weight as I have lost 25 kg myself since last outdoor cycling, but the wheels were straight and didn't wobble as the original ones did.
And do I love the freewheel sound of the Mavic 360 hub? Yes, yes I do!
Thoughts and conclusions
To my surprise the SRAM Eagle was quite easy to install, once you have all the tools (that I did not have when starting out).
I really like the SRAM PowerLocks compared to the Shimano pins that you have to install using a chain-breaker. It's such a pain to do.
Note for future is to get another torque wrench for the high torque bits like the cassette installation or the bottom bracket and crankset. At the moment I just figured that 50 nm is me using what force I can muster and when it stops it stops. Getting a torque wrench that goes from 20 nm and up to at least 60 nm would be a nice complement to my current torque wrench that goes from 2 nm to 24 nm.
It took me 2 months to complete the upgrade, but mostly as I really don't have the strength to work in longer stretches at the moment and the fact that I have been at the hospital quite a lot during that time. In real time, it might have taken a couple of days. So maybe a little big of a project for one weekend but maybe OK for two?
Would buy again.
