my bike is: https://www.giant-bicycles.com/au/xtc-27dot5-2-2014 and everything I have came with the bike, only now the axle of the rear wheel bent and the skewer has lost its grooves.

and I would like to replace the rear wheel with the 12 x 142mm version of: http://www.chainreactioncycles.com/au/en/easton-ea70-xl-mtb-rear-wheel/rp-

I want to reuse the old casettes and disc break. I was told to buy new rotor bolts, will these do? http://www.chainreactioncycles.com/au/en/hope-steel-disc-rotor-bolts/rp-prod9950

Will I be able to migrate all my previous parts onto this new wheel and will the wheel fit onto my bike?

update: A replacement axle would be prefered. What axle would work for my bike?

  • I'm really puzzled by your statement 'the skewer has lost its grooves.' (here and in your other questions bout this wheel) Can you clarify, or perhaps add a picture? I ask because this might shed some light on what is broken in your hub. Or point to some other damage to the bike you may need to address. Jul 12, 2017 at 11:53
  • @ArgentiApparatus - the teeth on quick release skewers do wear out, especially if they haven't been clamped down properly.

  • @Batman - I just didn't understand which grooves were being referenced, but I now realize the OP means the radial grooves on the inner surfaces of the cam block and adjustment nut. Jul 14, 2017 at 21:58

Unless the Oz version is different from the US version (which it doesn't seem to be; the picture is the same), it looks like this bike uses a by default regular old 135x5 mm quick release, so the wheel needs a quick release compatible hub (not a thru axle hub).

Have you tried servicing the existing wheel? QR skewers and new axles are way cheaper than a new wheel (but of course, thru axles are stronger, so the upgrade may be worth it anyway).

Edit: It looks like Giant has a conversion kit you can buy to go to 142 x 12 thru axles wheels.

A picture of the kit is here:

enter image description here

Looks like the two pieces on the left screw into both places where the skewer passes through, then the hanger is replaced as well. You can see this video on how to install it.

It also looks like you need a particular thru axle specifically from Giant due to threading; it looks like its a re-badged DT Swiss thru axle, so maybe they have something compatible.

  • yes a replacement axle would be preferable to a new wheel. But what do you think the measurements of the axles would be?

    Take the old one to your bike shop, or just take the wheel to your bike shop and tell them you need a new axle. They should be able to figure it out.

  • The most common axle for a rear QR hub would be 10mm diameter with 1mm pitch threading. For 135mm frame spacing the axle is usually 145-147mm long. However, some hubs use somewhat specialized axles so it's hard to say what exactly will work for yours without taking the axle out. Taking it to a shop could be your best bet. They would hopefully have what you need in stock. Jul 12, 2017 at 17:03
