    putting a normal steel axle into an M975 XTR rear hub?

    ok, i have a broken XTR hub axle, these take 3CN 9804, oversize alloy axle.

    Can i put an XT steel axle in there? i realise there'll be extra space around the axle but will the cones line up with the cups ok, or not? Madison UK say you have to use the XTR axle, but it's expensive and likely to break again.

    obviously an XTR axle wouldn't fit in an XT hub.

    thanks!

    i mean of course to use the cones etc from XT also.

    i guess what i'm asking is:
    Are XT and XTR cups same size?
    i know XT uses 1/4" loose balls and XTR uses smaller 3/16 caged, which implies they aren't the same cups? can anyone confirm please?
    there'd be extra spare space around the axle but not sure this matters.

    or, any aftermarket stronger axles, steel or Ti for XTR?

    from what i've read loads of people have this issue.

    there are aftermarket Ti normal (XT) axles, but not for XTR afaik?
    sad thing is, shimano used to use Ti for the XTR axle, until probably cost cutting killed it?

    even I could have told them Al isn't tough enough for an axle!

    Let me guess you don't have a hardtail either? on most/many? full sus frames the axle is also binding the two sides of the rear triangle together so it has to be very strong..

    would love to know what bodges people have come up with!

    and anyone purchasing wheels: stick with XT or go for another brand of hub unless you're a racer who can afford to throw away 40 on new axles regularly. XT steel axles are around 20 and probably compatible with Deore etc which are more like 10..

    Yup full suspension. I'm from aus, count yourself lucky my lbs wants $85 aud for it (~60 pounds). Oh well looks like I'm getting one shipped across from the uk unless someone else chimes in with a better option.

    Note that the XT 775 hub uses an aluminum axle (15mm) similar to the XTR.

    Most of the highend after market hubs also use Al axles

    The trouble with common sense is it is no longer common

    thank shiggy, i'd forgotten there are two levels of XT. M775 is something i can afford too.

    anyone confirm M775 axle fits M975?

    i'll go hunting tech docs later

    update: confirmed! shimano rate it "B" meaning it works, but isn't identical. result!

    p.s. i love On-One in the UK, good luck in the US

    Don't ship to aus

    Just called the lbs they've quoted $40 now instead of $85.

    Still get screwed, but meh. Thanks alot smiff for the research and shiggy. Let's just hope this is stronger than one double the price.
