Hi,

I got a cheap commuting bike. Wheels have never been servicing. Got it since at least 2009 and it has 10000+ km on it. I can feel the friction in the wheel when I hold it in my hand and let it rotate.

Local bike shop mech. told me the wheels might need new bearing + cone. This is a cheap bike from canadian tire. I was thinking replacing the wheels but it is just not worth getting new wheels. Plus it is a 7 speed bike.

Anyway, is there anyway to know what the bearings & cones are? Is there an easy way to go (replace the whole hub)?

Cheers!

Take it apart?

Would look at the cost of a replacement wheel before looking at repairing that. My LBS just replaces that sort of wheel as the part cost more (when workshop time taken into consideration) than a new wheel, suspect it will be similar for your LBS.

If you really want to repair it, the only real source for generic wheel parts is Wheels Manufacturing, all good LBS's should stock/be able to get their parts, if they (WM) have any that it is another matter.

What make and model hub?

Your hubs may simply need to be serviced (cleaned, new grease, adjustment), but you will have to open them up to find out.

If the bearings are "loose," they're cheap and easy to replace; your bike shop can quickly measure them if you don't have the tools to do so.

Cones are usually pretty durable, and I think it takes a lot of abuse/neglect to damage them. Inspection and a good cleaning may be sufficient. If not, depending on your hub your bike shop may be able to find suitable replacements.

Most difficult is replacing the whole hub. If you don't find a hub with the same build measurements, you would probably have to replace the spokes as well, plus the price of the build. Then you are probably near the price of buying new wheels anyway.

Unless you are afraid to take it apart and want to ride it til it fails you need to disassemble and see if parts are needed (pitting or uneven wear). If not just overhaul, if so then see if parts are available.

The wheel is a Xero 220. I am not looking to do it in a LBS, they are too expensive around my place (despite heavy commuters traffic) + I am a poor student . I prefer to learn how to service my bike.
I have access to very precise instrument, I am confident I can check the diameter of the bearings easily. I will take apart the front wheel soon and come back with pictures!
