I just thought I'd post a pic of my project bike before I get started on it. I'm going to build this bike up as a single speed or fixed gear, I'm not sure which yet.
It has a 6 speed freewheel on it now, is it possible to convert the freewheel into a fixed gear?
Regarding cranks, I assume you use a standard double crank and leave the outer ring off?
(sorry if these questions have been asked and answered before, I guess I'd better go read through the previous posts).
