Hello People. Is there any reason why 26" mtb wheels shouldn't be used on a 700c frame? Having bought a 700c hybrid frame (135mm spacing) with disc brake only mounts I'm finding it difficult to find cheap 700c disc hub wheels. I calculate that the difference in the height of the bike will only change by about 2cm. I'll be fitting reasonably chuncky tyres for city communting. Cheers, Pete.
