I have a 10 year old Trek 7300 FX hybrid which came with Matrix 750 double walled rims. "559 x 19" is marked on the sticker of these rims. The tyres fitted are 700 x 38C (622) - I'm assuming (should I be?) that the rim/tyre combination give me a 700c wheel?

The problem I have is that the freehub on the rear has gone (there's a crack on the inner cone section covering the bearings) and so it's not freewheeling without locking the chain up, and I'm thinking about a new hub and spokes versus a set of new wheels. Looking at the hassle versus cost savings, it seems that Amazon will provide a decent set of wheels spoked, hubbed and tyred for around £60 whereas a wheel rebuild might save me about £10 to £20 on that amount.

Any ideas?

    If it is 10 years old then the rims don't have a lot left. Get a wheelset. Or just a rear wheel.

  • Thanks Blam. Don't know what to go for though. We're only talking an occasional commuter bike that are worth £80 on eBay, so it would be daft to spend £100s on new wheels. So I'd be looking for a set of good quality budget wheels. Any recommendations? A bit of a minefield. Don't know what's good, bad or ugly LOL

  • Why two wheels if the front is OK - especially on a bike that is not worth much? You pretty much get what you pay for. I know US $. How much longer do you plan to ride the bike? Can get a decent single even in a bike shop for $100. Or you can spend $600+ on a higher end set. The other factor is newer bikes are going disc so if you got a new bike with disc you would not be able to use it/them.

  • Fair enough. I'll ask my local suppliers what they think are good wheels. Ultimately, I just want something that gets me from A to B reliably, and for 10 years, the current setup has done that. I'm not looking for anything high end because it'll just end up getting stolen by people with bolt cutters when I park it up shopping etc. Thanks :)

    As far as I know, all 7300 FX's are outfitted with 700c wheels.

Freehubs can be removed from the hub and replaced; it involves removing the axle from the hub and then loosening a fixing bolt with a 12mm allen key.
Visit your local bike shop and ask if they have any thrashed rear cassette wheels; if they're cool they'll give it to you free or next to free. Pull the freehubs and hope to find something compatible; there are several different spline patterns.
