What size fender did you use 45mm ?
I posted my 650b conversion on the thread awhile back, but recently converted back to 700c for commuting/wet weather riding. I miss the larger volume of the 650's but the narrower tire is a lot faster on the paved routes I'm riding these days. I also have to say I was wrong about the handling being overly stable with a 700c wheelset in my first post. At the time my handlebar was too wide, stem too short and bar too high. A more aggressive roadie setup has made a huge improvement. I'm jealous all you guys in the thread with the 2018 Exploit. The silver/grey frame looks awesome.
I noticed you're also running a set of Handsome Mud Butlers. I'm still getting a lot of spray around the bottom bracket and was wondering what you made your flap out of. Is it just a piece of rubber mat or did you adapt a flap made for another brand?
