I remember seeing an adapter from Mavic to adjust rear canti mounts up enough to work. Is there anyone else that makes something to accomplish this? I know I could run discs, but I don't want to have to buy a new wheel.
I found this while researching the same idea.
these brakes too. more expensive but a cleaner looking solution. http://www.paulcomp.com/frmbrakes.html
My fixed gear started life as a 26" wheel bike. A standard reach front road caliper matched the fork to a 700c wheel perfectly. I can't say for sure about the rear because I don't run a rear brake.
