Can anyone tell me the difference between these three Shimano disc brake adaptors? SM-MA-F180 P/P, SM-MA-F180 P/P2, SM-MA90-F180 P/P
They are all to convert a post to post front brake calliper from 160mm rotor to 180mm rotor, but look quite different in the pictures, and I don't know which one to buy. Help, anyone? Thanks.
The first one is the original design, the second one is a revised design and the third one is the XTR version which is cut out to make it slightly lighter. They will all do the same job, I have the XTR version because I am a tart but the weight saving in negligable.
Thanks Mister P - thats just what I needed to know! So the XTR one isn't XTR callipers only - it'll work with any Shimano post mount calliper - mine are entry level M445s?
And as it's only a quid more than the basic one, I guess I'll be joining you as a tart!
