So everyone is on the same page, some terminology. You have a wheel. It is made up of a hub, spokes and rim. Apparently the races in your hub are damaged. You want a pair of new wheels. You can use your old tires on your new wheels. It will be best if you can post a pic of any labels on your wheels and a pic of the cassette or freewheel so someone can ID which and how many cogs. Should be easy to find what you need.
