Hi all, as it stands I currently have a Raleigh Sport, mostly classic restored. The non stock parts are stock from an older Raleigh Superbe I own as a parts bike. I'm toying with the idea of tearing down my raleigh sport and building up the superbe, then using the sport as a single speed or fixed... dunno which yet, but here's where the problem happens. I want to switch over to 27" wheels instead, I'm worried about the axle spacing and clearances though, I think I have a front fork though that wouldsolve that problem, but what about the rear? And does this really help with the clearance of the pedals and make the bike better or is this just a folklore following of doing this?
