    FH-M785 "complete hub" compatibility

    Hey, this maybe an old topic and thus I can't find any relevant information - is this replacement axle kit interchangeable between fh-m785 142mm axle? In other words, can I use this to downgrade (I know, stupid) the 142mm TA axle set up to 135mm 9m QR set up? It seems it does, but there is no use case described in any retail sites.

    Thanks

    I figured I would update this. I got the hub kit, 135mm QR aluminum axle for my Santa Cruz Highball single speed. Y3TG98030 is the parts number. Ran this for 10 months, noticed some wiggle the other day, turns out the axle was snapped in half where the bearing race sits on. Would regular cheap o 135mm QR fit on this hub? Anyone tried non-aluminum axle on this, in 135mm set up?

    I would check out wheelsmfg.com for replacement axles. It may not say specifically "fits XXX model", but if you match the thread pitch with the thread pitch of the axle you previously purchased you will be good to go.
    Silly bike things happening.

    Shimano warrants components from failure for 2 years. Give them a call.

    Update - I haven't thought to call Shimano, I will give it a try.

    I realized that 135mm aluminum axle is smaller in diameter than the 142mm cro-mo axle. So the end caps for the aluminum axle won't go on to the cro-mo axle. That means the only axle I can run with 135mm 9mm QR High Ball swinger dropout is this aluminum axle. That sucks.

    Performance online has the axle only option at a wee bit cheaper price, so I just got that. Will see how long this one lasts.

    The bottom line, 135mm setup is dead, I need to move on
