Most shims are 34.9 to 31.8 or 34.9 to 28.6, think you will struggle to find one that is 31.8 to 28.6, although I think there was an XTR m960 shim of that size.

Also, in case you didn't already know XTR m950 is designed for 8 speed.

Should be getting a Kilauea frame later this week & will be similar build but with rigid forks & XT m770 groupset :)

I was in the same boat with my cindercone build a few weeks back, couldn't get a 28.6 tp m750 mech so I made a shim to fit my 31.8 version.

I've since found the correct size mech, so this shim is spare?
I'm still struggling to find a carbon 27.0 seatpost that's not a kings ransom though :(

road mechs have 31.8mm > 28.6mm shims quite commonly, all alloy too so you can shape them to your clamp 8)

good idea with the roadie mechs, will check out :)

yes, I know that the 950 series had been designed for 8 speed use, but the cage is wide enough to be capeable of 9 speed usage, too.

I've run 8 speed FMs on 9 speed but IIRC 9 speed FMs are a touch wider??

slow progress at the moment, bit of summer break

latest component I got is the BB

CrankBrothers cobalt XC

Image

I think its a quite good compromise in between weight and lifetime

current weight of the build is 8409 gr. with still some parts more to come:

-crank
-chainrings
-chain
-chainringbolts
-BB bolts
-pedals
-liners & cables

hope to achieve arround 10,8 kg
