I would like to change the rear axle spacing on a Mavic Ksyrium ES hub from 130mm to 135mm (I want to use the wheelset on a Cyclocross frame with 135mm spacing). Is that possible / practical? If so does anyone know what parts I need and where I can get Mavic hub parts?

Thanks.

If it's not just a matter of buying a MTB spindle and 5mm spacer, I'd imagine Mavic do a MTB hub with the same bearing arrangement; it should be pretty straightforward to get the bits you need.

Years ago, I realised my Giant CFR1 had a 135mm spacing for some reason... rather than bend the carbon stays every time I did up my wheel, I did this trick and enjoyed a stronger rear wheel with less dish : )

There's really no pressing need to replace the axle. Undo lock nuts, shift axle over a tad, add spacer(s), put lock nuts back, adjust bearings if required.
The main force holding the rear wheel in place is the clamping force of the q/r, a few mm of axle protrusion into the dropouts to guide the wheel into position is plenty.

And just how are you going to shift an axle over that is shouldered in places to support the cartridge bearings inside the hub? The end caps on a Kysrium ES are press fit. You can't shift anything over. Which is why the whole point of this thread boils down to whether or not mavic's 26" wheels have a compatible axle that is 135mm that fits his ES.

I run an Ultegra hub/Mavic Open Pro on my Trek 520 touring bike (135mm) most of the time, though I also have a set of Deore/319 wheels.

My favorite mechanic changed out the axle, added a spacer, and redished the wheel. This removes some of the dish (lower tension) on the drive side.

Again, this is not the standard 10x1 shimano QR that are so readily available. That axle is a proprietary mavic design.
