Just got done with this build:
Fun to build, fun to ride. This is my third fixed build... if you count a roadbike conversion or assembling a Windsor The Hour from the shipping box. So I'm calling it my first build from scratch
Got the hubs from United Bicycle Supply a while ago, built them up with full blackout treatment--black hubs, black spokes, black nipples, black HPlusSon rims. 36h is all the hubs come, wheels are 3x lacing front and rear. Strongness.
Boss ordered a track bike because I begged him to get one for the floor. He said he would, but if it didn't sell, I'd have to buy it at cost. Um, OK... 09 frames were the last year they were welded in Waterloo; from 10 on, they're coming in from Taiwan.
Took a while to get gumption up enough to drill into a perfectly good new frame in order to pop-rivet on the front cable stop. Once that happened, the rest of the shifter cable setup and adjustment was a piece of cake. Pulley is a Problem Solvers clamp-on.
Limited riding, so far, and I'm not a dedicated fixed gear rider, so not much decent feedback I can give. Play in the hub is not heinous, don't imagine it will be an issue for anyone used to dealing with a slightly loose chain. Might require a bit more regular attention to chain tension.
Hub feels a bit clunky, like any other SA 3sp; shifting is kind of particular--no shifting under load, although upshifts seem to work better than down. Pick the gear you need before you need it, or it will be a real momentum killer.
I really like the way it turned out.
