Been on the look out for a front for a while, my spare was on one of the bikes that got pinched. Thought I had found one on the Canyon sale site when we ordered some of the 29er Pikes but it was a European left hand when it arrived.
They now have a European right hand rear brake on the site so I took a punt and ordered it. Arrived today, just need to shorten the hose
Front left hand is £58.95
Rear right hand is £36.95
203mm post mount adaptors are only £2.95
If you need a pair its just a case of swapping over at the lever
