I have a Huffy Savannah 27" bike that I bought about 6 years ago and need to find a replacement rear wheel. The bearings went bad, but the rest of the bike is almost brand new. The tire is a 700c x 38. How can I find suitable replacement? I don't care about brand, only that it will work with the tire.
New ball bearings will cost less than a new wheel - the order of $5 for a bag. It may be that your bearings are okay just mal-adjusted so there may be no cost for parts.
You'll need a cone spanner and a conventional spanner, some grease, and cleaning gear (rags/ solvent like petrol or whatever)
Since its the rear wheel, you'll need the special tool to remove your cassette/freewheel as well. Even buying one of these its still cheaper than replacing the wheel.
This is a good start:
Another option is to find a bike coop in your city and ask for some assistance. Wheel bearings are straightforward fixes.
If you don't feel that you can do this, a bike shop can change your bearings for half the cost of a new wheel.
