| now someone may correct me if I am wrong. but I believe that the r series bikes have different carriers than the general spec bikes. i.e those with Ohlins front forks as standard.
if you look at the inside of the fork leg where the calliper mounts up you will see it has been machined away.
I had some 5mm shims made up by Yeti to put the calliper back to where it should be. and that's all you should need |
