Hey all, I'm putting together a fixed gear/single-speed bicycle based on a Raleigh Technium road bike frame. I've been wanting to build one for a while now, and while I intend to ride it all year I was looking forward to taking advantage of fixed gear traction and maintainability for snow riding. To that end, I was hoping to slap on some cyclocross tires with a good tread on them, but I'm quickly coming to the realization that that's kind of a naive idea given the clearances of a standard caliper brake and road fork. Has anyone tried this? Are there any combinations of tire size/caliper that will work okay, or should I give up on this idea entirely and just wait until a cyclocross frame with actual cantilever bosses comes my way to build the tough winter bike I had in mind?
