Rear axle sparer

    I'm attempting to resize a rear wheel for a 135mm spaced hybrid frame instead of a 130mm spaced frame.

    Can I use any correctly sized washers for this? Specialised ones seem thin on the ground.

    How far past the locknut does the axle have to protrude to be considered safe? Sheldon says "even 1-2 mm protrusion past the lock nuts will suffice", although that sounds like very little to me.

    In the short term I plan to space it evenly on each side and not redish the wheel as I don't have a wheel truer or dishing tool. What's the downside to this other than possibly having gearing issues?

    Two questions arise:

    1. What material is the frame? If steel, it may just squeeze in to fit the 130mm axle, if alu/carbon, maybe not.

    2. Should you buy a 135mm axle and fit that to the wheel instead? This would be a permanent resizing rather than a temporary one.

    As for redishing, adding spacers to both sides will move your gearing off so that you have to do a full readjustment. If this is a permanent change, then my question 2 above applies. If question 2 applies, you should redish to suit a new axle. If it's not permanent, what about question 1?

    thanks cdaly.

    1) Aluminium frame. I've read you can just compress it down with the skewer but you may eventually crack the stays, or break the skewer if it's poorly made.

    2) Correct me if I'm wrong, but my understanding is that it's not so much the length of the axle but rather the space between the locknuts (which usually includes spacers anyway). i.e. even if I were to change the axle for a longer one, I'd still need new spacers, so the only reason to get a new axle would be if the (for example) 2mm past the locknuts on each site wasn't enough.

    There's no doubt that redishing is the more correct way to do this, but I'm not really equipped/skilled to do it so may end up buying a different wheel if it comes to that. So, I'm looking for a solution that gets this frame out of my shed in the short term, rather than a longer term solution.

    I'm currently inclined towards going to the local hardware shop and measuring up some washers, so I'm looking to have that plan sanity checked.

    That sounds reasonable. You're probably gonna have to readjust the gearing in any case.
