I built my own after tying out a suicide with a proper track hub - something your local bike shop might find amusing but should be able to do nonetheless.
So how did you like it? I've never ridden a fixed but the idea really appeals.
I have a set a BMX wheels that I bought second hand for my Twenty project. The rear wheel has threads on both sides, but one has a smaller diameter than the other.
How can I tell if it’s suitable for a fixed wheel? What would be a recommend gear ratio for a fixed Twenty with a newbie rider?
