trials isn't my main thing...i just like messing about on small walls, kerbs etc so didn't really want another bunch of wheels which are not 135mm. but if there is a common source of 116mm hubs...that'd be great. didn't really want to go front freewheel due to expense. as it is, i build my trials bikes with mtb parts....of which i have loads. but my adamant frame turned up yesterday....and it's not 135mm spacing. if i knew this, i would have probably got another frame...so i can still use mtb parts. i can build wheels so just need to know where to look for a cheap source of 116mm hubs!
