UPDATE: Reviews section refreshed, redesigned, searchable: Go take a look
I'm getting a new M4 back break and want to know what size rotors are compatible. I also have an old style M4 on another bike and want a bigger disc on the front than the 180mm one I have at present (the forks are Pikes). Is there maybe some kind of chart available for rotor compatibility and do I need an adaptor for the old M4 or are they designed to fit straight to the post?
Thanks
?
You can fit a bigger rotor but will need an adapter
Which adapter you need depends on calliper, rotor size and mounting type
There is far more info on the hope web site
For older is mount systems you can get plus 20 and plus 40
Brackets
Thanks that's just what I needed. Thought it must be on the site there somewhere.
