I am very interested in building a fixed gear bicycle. The base bike I have is and old fugi sports 10spd with a freewheel. I want to olny build this bike out of the parts I have (I have ALOT of old road bikes around). What is a good gear ratio to make it?, (It is fairly hilly around here). And am I supposed to screw a cog right onto the hub threads. Other than that I would greatly apreciate tips about building and riding fixed gear bicycles.
I have already visited this page:
Just wanted to see if I could clear some things up
