Got a few road bike wheel questions for those in the know. The bike is a 2000 (I think) Cannondale R300 triple ring with a 7 speed cassette.
Front wheel: has constant unusual vibration that appears to be coming from the axle. I don't know what it is but I imagine it can't be good or normal since my other bikes don't do this. Is the wheel shot? Am I in danger of riding with this problem? Do I need a new wheel or is this something that can be repaired?
Rear wheel: quite simply, it has a crummy old Sunrims CR18 on there that's getting pitted and out of true. I'm not beyond replacing the wheel.
I don't need high performance stuff: consider me poor. Is it generally cheaper/wiser to have a new rim spoked up to my old hub, or is it more cost effective to simply buy a new wheel and throw my old cassette on?
