My girlfriend has had the wheels stolen from her bike. I'd like to replace them, but we're working with a limited budget so I'm going to do the work myself and source the parts second hand.
I've done a basic bike maintenance course but beyond that I'm relatively clueless. I know that the new wheels need to be 700C's, and that the new rear gear cassette needs to be 7-speed (I guess because that's what the gear shifters are) but I have the following questions:
- Will any 700C wheel work with any gear cassette? From browsing eBay it seems that some of the wheels are specified as working with 7-speed or 8-speed cassettes?
- The first question aside, will any cassette screw on to the mounting on the wheel I buy, or are there different threads?
- Should I buy a free wheel or a cassette? I'm not even sure what the difference is!
