New rear axle assembly required.

I removed a rear axle yesterday after I noted the rear wheel to be wobbling.

The bearing race looks very pitted and needs to be replaced.

Is it best to replace the whole axle assembly? If so, any ideas where I might pick one up - ebay?

It looks to be 149mm long, the bearings are loose as opposed to being in a cartridge.

The bike is an old Scott Chenoa, the wheel says Alex Rims with a ‘Formula RBP’ sticker on the hub.

Many thanks

    An axle wouldn't come with a race, if you can even replace it.

    A new cheap wheel would probably be the easiest.

    Formula probably use a generic cup and cone, so most bike shops should be able to get one.

  • A decent bike shop will have a spindle and cones. But if the cone race is badly pitted then it is highly likely that the surface of your hub bearing is damaged also. So you would need to carefully sand it down or replace the hub or wheel

    Sand it down, really?

    Just knock out the cup and replace it.
