I've been collecting parts for this build for a while but it's finally coming together. Here's the parts list.
Karate Monkey frame set
Shimano Nexus 3 speed disc hub & XT hub laced to DT Swiss rims
King BB, RaceFace Atlas cranks, BB7 brakes, XTR levers, RaceFace bars and stem, Woodman headset, Thomson post.
I'd like to use a thumb shifter but my research has come up with varying results. Has anyone been successful using a thumb shifter? Or any other shifter besides the grip shifter?
