It might, depending on clearance. It's probably one of those things that you'll have to measure.

Discs will work on any frame and fork with the mounts for them, and a wheelset with disc-specific hubs. Changing a tire with disc brakes is easy- no brake to open with frozen fingers. My next commuter frame will be disc-compatible for sure.
