....being new to all of this I had never even heard of disc brakes until someone recommended them. Where I'll be biking, there lots of hills, so I guess disc brakes are good? The sutra's got 'em and they were pretty cool. The only thing I've been wondering now...how hard is it to remove a wheel to change a flat with disc brakes? As it is, it takes me *forever* to change a flat on a bike with cantilever brakes!!!

Potential disaster for me and disc brakes????
