I've got a 2002 Trek Fuel 100 carbon frame that I am refreshing/upgrading. I bought a pair of Avid BB7 brakes to install. But I don't know what IS adapter to get/use. The included adapters are too long (bolt holes spacing)
The rear dropout of the Trek has a set of "IS" holes to mount a disc brake that are about 44mm apart. I.e., closer together than the 51mm standard that the included adapters are.
Does Avid make a "44mm" IS adapter? And, if so, what stand-off height would I need to get the caliper positioned properly for the 160mm rotors? Is there a way to calculate this?
Thanks for any help for a Disc Brake newbie
