Adaptor for IS caliper to post mount fork....

wadsy · Jul 6, 2017

I have some M975 calipers (160mm disc) that are IS mount and need to fit to a post mount SID....what do I need?

Most adaptors I've seen are threaded to mount to the fork, but the post mounts on the fork are threaded so I would think the adpator should have a clearance (non-threaded) hole???

Cheers

this - http://clee-cycles.co.uk/P1043/product though you will need to go up to 180mm disc.- otherwise caliper will foul mount. exact same brakes - m975

I really don't want to go up to a 180mm disc; I have M975 discs that are centre lock!....is there no alternative? :?

in my experience no - unless you want to dremel the caliper or the mount- there is not much metal to play with safely. Ruled it out as quite attached to having a working front brake that doesn't shear off and feed itself into front wheel. Had to buy new disc myself though rt81 - considerably cheaper than xtr - hardly any weight penalty either.

From Taiwan tho'.

I think I have a +20mm a2z adapter. If I can find that you can have it for £5 posted. Not as pretty as the kcnc one but cheaper!
