    Hub rebuild question

    My 1991 Diamondback's front wheel has a Shimano Exage hub that is possibly in need of a rebuild. I imagine this is a fairly inexpensive hub. Any way, it makes noise when riding and you can feel the friction when you spin the wheel on the bike. If it does need a rebuild and I can get the bearings and cones from a bike shop is this worth the rebuild?

    Thanx for your reply

    Disassemble and inspect the cones and cups. If the cones are pitted but the cups are smooth, then the hub is rebuildable with a replacement set of cones. But if the cups are shot, it's time for a new hub. Shimano doesn't market replacement cups for their low-end model hubs, if any.
    Bearings are 3/16" Grade 25. Bag of 100 should be $4. Cones, under $10 for a pair.
    A new hub can be found for as low as $10 (deore LX). But you'll need to relace the wheel and true it. Unless you know how and have a truing stand, expect to pay $.
