Thom Posted January 17, 2007 Report Share Posted January 17, 2007 What size rotor would I need if I used a 160mm front avid on the rear with a +40 disk mount on the back ? Thanks in advance. Quote Link to comment Share on other sites More sharing options...

Thom Posted January 17, 2007 Author Report Share Posted January 17, 2007 sorry, I want to use rear disk and the frame has a +40 disk mount on it. I have a avid bb7 with a front 160mm adapter that I want to use on the rear. What size rotor would I need ? Quote Link to comment Share on other sites More sharing options...
Waddy Posted January 17, 2007 Report Share Posted January 17, 2007 180, as on a standard rear dropout a front 160 caliper will be 140, so if its +40 it will need a 180 disc, (140+40= 180) Quote Link to comment Share on other sites More sharing options...
