OK, so I've read the rules for newbies and I'm going to try not to contravene any of them. Whilst I am a hugely keen bike rider, it has become abundantly clear to me in the last month or so that I don't have the first clue about bike repair or maintenance. Apologies if I break any of the rules here.
I buckled both my wheels in an accident a fortnight or so before Christmas. Being a student, I don't have much spare cash and I could only afford 1 replacement wheel. I bought the front one, and asked my Dad for a 7-speed rear wheel as my Christmas present. My previous rear wheel was of the 'traditional freewheel' variety, and of course the replacement I've been given is a freehub and casette dealio.
Basically my question is, if I pick up the necessary casette to go on my freehub, will this new wheel be compatible with my bike?
Please be gentle!
