I don't know about you guys but here in Montreal morning are getting chillier. I'm slowly starting to think about my winter bike. I want aluminum frame to avoid rust. I want try something new to me. Something call Disk (or Disc) brake. I never really work with disc brake. Is Disc brake bosses (the part of the frame or the fork where you attach the mechanism) are all the same for any disk brake. Or different attachment for different mechanism? DO you have good online ressources to know more about disk brake. I also want to use gear hub, something like the 8 speeds SA offers X-RK8(W) maybe the "what's about internal gear and subzero weather" question will be part of another post.
