    XT Hub w/ Solid axel - any better?

    Has anyone swapped out the hollow QR axle in place of the solid, bolt-on variety? If so, have you noticed any improvement over the standard QR axle? I don't have any beef with my QR setup (currently running with horz drops and a tugnut), but I was wondering if there is any benefit to going with a solid axle.

    I've done it and had no problems with slippage on a Karate Monkey frame. It makes for a pretty heavy rear hub though.

    wheels mfg M10x1 174mm qr axle should be a lot lighter than the solid one.

    Have you tried this? That would be a good option if it works.

    no. but other than the difference in length, there's nothing else that stops it from working as well as a solid one. your solid one is probably 187mm. how much sticks out of the nuts?

    According to the metallurgists type guys the added surface of a hollow axle increases strength over a solid one too.

    the proper question to ask is, do you need it? you can make a hub with 10cm diameter axles for good measure too, you know.

    I've since replaced the hub with a Surly.

    But with 135mm hub spacing and axle nuts needing ~15mm of space each, you'd need drop outs thinner than 5mm to make it work.

    I've replaced several XT and Deore hollow QR axles with 187mm solid nutted axles for use on horizontal frame mounts. The main advantage is they are designed to hold without a chain tug. The disadvantage is that you need to carry a 15mm wrench. The weight gain is not that much percentage wise since the Shimano hubs are pretty heavy to start out with.

    I carry one of these (in a 15mm version that is):

    Stubby Wrenches are available from various place including Sears, fit a seat bag, and give you a bit more leverage than the Jethro (and cheaper) - the disadvantage is no bottle opener.

    So by most accounts...

    ...the bolt-on axle reduces the chances of slippage, but doesn't offer any noticeable improvement in lateral stiffness. I guess I kinda expected this. Thanks for the replies.

    never had a leverage prob with the jethro as it has a wide palm perch, stubbies dont. jethro is 4" long, most 15mm stubbies are about 5" long, whereas my seat bag is only 4.5" long. a single stubbie is much cheaper though.

    i ride with a mule 'bak (lots o room) and used to carry a cheap 15mm socket and driver!
