liam n Posted May 2, 2011 Report Share Posted May 2, 2011 hey , small question, if i get a 203mm bb7 adaptor, can i get any bb7 size calipar and it will fit on? cheers matt I'm not definately sure, but i doubt it, there set up to use as much pad as possible at 203mm, you go lower with a caliper and be using less brake pad?.... but why do you need 203mm anyhow, if it's on the front, you'll be fine with 180mm for a stock, BB7 are pretty damn goood Quote Link to comment Share on other sites More sharing options...

Nick Manning Posted May 2, 2011 Report Share Posted May 2, 2011 All Avid disc brake calipers are the same size, regardless of being cable operated or hydraulic. What determines the size of rotor required is dependent on the adapter size. A front avid disc caliper will generally use either a 165mm, 185mm or 203mm adapter. Remember all Avid calipers are post mount, so check what fitment you need. For trials forks it will be a IS to post mount adapter. Quote Link to comment Share on other sites More sharing options...

Nick Manning Posted May 2, 2011 Report Share Posted May 2, 2011 so if i had the right 203mm adaptor i could buy any bb7 and it will fit on my 203mm rotor , correct? thanks for the help nick yes that is correct Matt. I myself am using a BB7 with 185 rotor, I bought it with a 165 set up, just changed the adapter and was ready to go. Quote Link to comment Share on other sites More sharing options...
murph82 Posted May 3, 2011 Report Share Posted May 3, 2011 yes that is correct Matt. I myself am using a BB7 with 185 rotor, I bought it with a 165 set up, just changed the adapter and was ready to go. I have a 203 rotor with a bb7 mounted on an a2z bracket on some saracen forks no problem! Not sure if i added a couple washers to the calier bolts though to space off a little more?
