Evening all just about to buy a set of M785,s from rose.
Iv,e got a pair of new avid g3,s 160 and 185.
Can i use the avid mounts with these.
Iv,e got an avid 160 rear and 185 post front mounts.
Cheers all.
If you use the mounts which match the brakes there shouldn't be any problems. Lose the 'tri-align' spacers/washer from the avids though.
This evening I fitted xt brakes to my mates bike and he had g3 rotors The exact set up you are describing.
I fitted Them fine with his existing post mount but I did find the pads where very Close to his rotor as if the g3 was thicker then the shimano rotors and I fear if these had new pads in them they may be bind!
How ever I got them running freely.
I have a funny feeling they may be loud and squeal, a quick google showed a few people who used g3 rotors with xt brakes also found them noisy.
The xt brakes I fitted last night with g3 rotors worked fine today no noise or braking squeal!
All good on this bike
Someone posted on a thread a few days ago that avid changed the design of g3 rotors because they had a propensity to squeal (hence the wierd looking ones as seen on CRC and some 2011 bikes with no cutouts near the centre). But squeal aside, superficial and zoota have it: leave the spacer thingies off and it will be fine.
Cheers zoota.
just what i wanted to hear.
Ta bud... 😀
