I've been helping a heavy friend of mine build a road bike for him self. Until now he's only been able to ride mountain bikes but we found a old trek 700 frame thats 65cm. I have some nice 48 hole tandem wheels which I was thinking of re spacing for his frame [120mm in the back I think]. My question is, can I expect a well built 36 hole wheelset to work or should I take on the tandem wheelset. The problem with the tandem wheels is that the rear wheel has a thread on drum brake which makes the rear spacing screwy. It would be easier to use some standard 36h wheels.
