so looks like an expensive lack of research 😳 can anybody definatively say if an m665 (2010 ish)lever will work an m675 rear caliper(2013) thanks

Yes… I have that setup and it works nicely

yes, will do.

thanks for the replies now part 2 of question ,where to get hose kit and long banjo bolt for not much money ..running out and still need rear mech

Hose

The Banjo Bolt “should” come with the calliper if the picture is anything to go by, but worth checking before ordering..
