Proper way of choosing hubs Not a product rec question, I mostly need to know the way of selecting the correct hubs for me.

I've got a GT Avalanche 9R expert and I'm not happy with it's hubs.


I use this bike only for xcm and other off-road riding - as I understand I need to have a hub with industrial bearings (not sure if it's the correct word) - right? What difference makes the number of them? (Some have 2, some 4)
(A bit more specific one) That's what I've found in specs:




Should I look only for QR models of I can use 10mm through axle?


Now I have a center-lock rotor mount. Is it interchangeable with 6-bolt?
If you are having to service hubs after a 50km ride in wet and muddy conditions something is wrong. All bearings on modern hubs are 'sealed'; not hermetically, but enough to prevent ingress of water and dirt and should not need servicing so often.

Just to address you other questions:

Re 'industrial bearings' I think you mean cartridge bearing types (which use industrial standards for sizes and quality). You don't need these per se. Cup and cone bearings work fine.

You cannot use through-axles on a frame designed for quick release axles. Some hubs are convertible from TA to QR though.

Center lock and 6-bolt rotors are not interchangeable.

With inexpensive wheels it's not cost effective to replace hubs because new hub, new spokes and the cost of rebuilding the wheel is comparable to the cost of a whole wheel.
