I'm thinking of building my old Mongoose IBOC Pro-SX frame into a single speed. When I built the bike in 1997, I put a '97 Judy SL (63mm) fork on it. It was a sweet hard tail back in the day. It came in at 23.5 pounds. Anyway, the '97 Judy SL's axle to crown measurement is about 420 mm to 425 mm. Does anybody know what a to c measurement this frame was designed for?
