I ride a lovely freak of a bike. A '78 Motobecane singlespead with moustache bars and cyclocross tires. It's been clearcoated over the original paint and I love it. I use it for everything (commuting, road, light trails). I'm getting ready to build a new wheelset and am trying to figure out how to adapt disc brakes front and rear. Id' prefer to still use the comfy hi-rake original fork. Any ideas?
