do the rules for os raceing allow you to use odd shaped frames ? i remember, bitd, a kid on a cw phase one with a big lump of foam on the z bit , club level race obviously, so does the os bike you use have to conform to the old regs? i know its a 1" hset , caliper brake or rather a brake with a single mount point, what about post 85 Haro's with L dropouts? they meet the 2 standards but do the dropouts disqualify the frame ?
