So I just upgraded components on my Cannondale road bike and have a bunch of 105 components sitting idle. With winter riding around the corner, I was thinking that a cross bike would be the perfect solution for riding when the weather turns to crap up here in the Pac. NW. I'm thinking about picking up a Cannondale disc frame. I've got Avid mechanicals on my mtn bike and love 'em, so I'd like to go disc. Questions:
Anybody know the hub spacing on the C'dale disc frame? 130? 135? If it's 135, would I then need to get wheels built with a mtn disc hub and 700c rims? Also, what's the difference between the mtn disc brakes and the road discs made by Avid - just the spacing from the disc mount tabs to the rotors? I know this will sound like some annoying 4 year old - why are they different? Seems silly to me. Maybe I'm missing something. So many questions, so many miles.
