OK, more sagas with a bike i am rebuilding.....

The bike, according to the little cat eye the guy left on has done 8000 miles!!! i want to know how to tell if the rims have had it as well as the hub, rebuilding wheels i can do but its not worth doing if all i keep is the spokes!!!

Anyway, the wheels run true, and the brakes work. There is a small ridge along the top edge wear the brakes have caused some wear.

    Feel the braking surface with your finger tips. If they're noticeably dished then they're worn.

    Also, check to see if your rims come with a wear indicator (Google them!). Some rims have a groove, and when the braking surface is level is that they're worn, others have markers of a different shade which show through when the rims get thin.
    Sometimes parts break. Sometimes you crash. Sometimes it’s your fault.

    Thats what my LBS told me when I was (needlessly worried) that my rims had done ooh, er.. ?000s of miles :)

    If they feel nice and square, you don't really need to worry yet.

    Just you :D

    If your really concerned and don't trust your judgement, a cheap option is dental calipers. But they make most sense if you have a reference width to start with.
