What do about wheels?
 

I'm in a delema. My rear cassette is pretty sloppy. It's not unrideable by any means... it just worries me.

Now I don't have a lot of $$$ to spend on new wheels. So should I just buy a new hub and cassette and use my old spokes and arya rim? Or should I look for a full wheel and get it over with?

How hard would it be for me to install a new hub? I know how it all works, but I know I can't get it true. Would it be cheaper for me to get everything close and then take it in to my BikeShop to finish it up?

Now my final ? I really want to get a hub with an cartradge bearing. But I honestly cannot afford more than like $35. Am I dreaming here?

Thanks for putting up with the questions. I'm learning :D

I'm confused by your question. The cassette is replaceable independent of any other parts, so if that's where your problem is, just replace the cassette. Even if you buy a new wheel it won't come with a cassette anyway.

What do you mean by "sloppy?"

Freehubs are replaceable units, and not very expensive. You also get a nice shiny new bearing surface.
Shimano cup and cone hubs are hard to beat, even the cheaper ones are quite tough. Cartridge bearing hubs have no real advantage for the user, they are just easier to manufacture.

Usually the hub should last several rebuilds. It is the rim and spokes which need replaceing.

So I can assume that my bearing surface for the cassette is ok? I just assumed that since the cassette is so sloppy back and forth the surfaces were shot.

How do I go about getting bearings for that?

Your local LBS should have any parts you need to repair the cassette or replace it. As the other posters have said, you don't need new wheels.

OK so that aside.. lets say that I wanted to get new hubs for disks or whatever? What about the rest of the questions above?

DO NOT REUSE SPOKES!!!! You can reuse rims.
The hub diameter designed for a disc brake is probably larger than the hub you now have, This automatically means you have to replace the spokes.

There is no standard hub and wheel configuartion. There are differences in the number of spokes --from 12 all the way up tp 48-- there are hi-flange hubs and low flange hubs and some in between. Then there is spoke lacing --radial, cross one, cross two, cross three or cross four. Each of these configurations require a different spoke length.

The point is, your spokes probably wouldn't work anyway even if it were safe. Being thrifty is a good thing, but not if it will be unsafe.

Most shop I know of charge about $25. to build a wheel but only about $10. to true one.

Have n ocomment on your last question.
