I'm looking to turn my old raliegh mtbike into some form of roadie thing. First up would be the wheels as they weigh a hell of a lot more than my new mtbike's so I assume this could be a big improvement. Are frames a bit contributation to weight? It is an old steel thing. Whats a good lightweight 26inch wheel set for a resonable price. Say no more than £100ish. Don't need to be very strong maybe XC wheels of somekind.
