I had this follow me home from the bike shop. Yep, here it is, my fixed gear! I named him Malachi Constant, as that translates as "Faithful Messenger". (Yeah, and I'm a Vonnegut fan as well. )
Set up with a small moustache bar, and I did add a front brake. The crank is Bontrager Sport, and gearing is 44:12, which gives me a gain ratio of 7.3:1. In gear inches, that's 98.1 gear inches, and at a 100 cadence, that will mean 29 MPH. I've got a sweet honey brown leather saddle I may put on it, as well.
Pedals are Egg Beaters, of course. The frame is a mid 80's Nishiki Sport that's been converted to Single Speed. It has 36 spoke Alex wheels, and with the nondished build possible with a SS/FG, I shouldn't have any issues. The hubs are Schimano High FlangeTrack Hubs in black..
