There’s absolutely no reason to convert a perfectly good touring and adventure bike like the Kona Sutra to something other than what it is. No bicycle is perfect. People have different needs and wants. This bike happened to be a great commuter and touring bike. But I wanted something more. It is a great platform for upgrading. There wasn’t anything preventing me from doing it other than the expense. So over the course of a year, I waited: watching and comparing prices, gathering, mooching, convincing my SO of the need, nay, the destiny of my dear Kona. It must be rebuilt! I ended up with the dankest of dream builds.

I have had this particular Sutra since it debuted in early 2017. I was drawn to the metallic flake paint job and easy-going geometry. When commuting to work, I found it to be extremely comfortable. Out on the trail, it handled very well, making it not only an excellent commuter but a hardy adventure bike. With all the new categories of road/gravel/adventure bikes out there, the Sutra is like a do-it-most bike that seems perfect, albeit just a little too heavy. But that is Kona for you. Their frames are built very well. Steel, though. I will deal with the extra weight if I can have the durability!

Always on a quest to build my a better bike, stock off-the-shelf rides usually don’t last too long in my household. Even though this bike performs really, really well, I wanted to do a few things to it that required some major surgery. I agree that the bike is good the way it is, however, there is always room for improvement.

The Sutra standard (not the LTD) comes with a Shimano Deore mountain triple crankset. My relationships with the many front derailleurs in my life have been awful. Always adjusting, rejecting the new technology like SRAM Yaw and that tooth-pulling new Ultegra FD-8000 derailleur that Shimano dropped on us last year. I decided that the best place to start my Sutra upgrade was to convert the drivetrain to a 1x, and kill the FD with fire (seriously, I think i tossed in into a friends BBQ). I already had a Shimano XT M8000 crankset handy, but I wanted more teeth. I purchased a Wolftooth Components DropStop 38T chainring. Believe it or not, this part of the conversion was the easiest part.

The harder part was getting the rear derailleur and cassette sussed out. I really like the way the Shimano XTR Shadow Plus rear derailleur felt. For me, Shimano has always has had the smoother-shifting feel. Believe me, I realize that something like SRAM Force 1 would have been easier. But to build the dankest, one must be a bit of a nonconformist. Problem was, in order to use the XTR with the Ultegra shifters and the 11-42 cassette, I needed some Batman-style gadgets.

Wolftooth Components, being as clever as they are, had two nifty devices that I could use. The Tanpan pull-adjuster for the Ultegra-to-XTR cable path, and the Goatlink 11 which would allow the normally 11-40 XTR compatible with 11-42. Though it sounds like overkill, it actually works really well. The shifting is smooth and accurate. When routing the inner cable through the Tanpan, it must be really tightly pulled through the pulleys and the cable bolt. Otherwise, the barrel adjusters will have too much slack to tighten the action.

I also wanted wider tires and stiffer wheels. So, again, doing something completely unnecessary, I decided to build some 650b wheels. Both are 32 spokes, cross three, laced to WTB Asym i29 rims. I also put a DT Swiss 350 rear hub in the back wheel.

The handling is pretty nice. Even with the WTB Byway 650×47 tires, the effective diameter is still just short of what they were with the 700s. I need to get smaller cranks. Other than that, the bike handles like a dream. The stiffer wheel gives a great response on the road and the dirt. The wider tire certainly allows for better cornering and comfort as well.

Because I am always upgrading, eventually I want to get some Paul Components Klamper brakes and a new headset (suggestions welcome). I already have some Simworks Honjo brass Turtle 58 fenders that I need to tweak to fit as well. But that is for later. I hope you enjoyed checking out my dank bike.
