Hi all, As the title states I have no idea how to determine what my rear hub specifications are. My rear hub bearings still spin like new, but there is an off-balance somewhere with the rear wheel area. When I lift the back and step the pedal, the wheel spins well, but the bike rocks up an down slightly when holding it in the air. I tried searching the forum for hub and rear hub but to no avail. Could someone please advice me how to determine my current hub specifications and which of these are important to keep in mind when buying a new hub. I know the hub has the extra part for the disc brake rotor. It says "American Classic" on the hub I haven't counted the spoke-holes as I'm unsure if there are special things that needs to be taken note of. EDIT- added: Its a new tyre with a new slime tube (well, it rocks heavily whether I have the road slicks on or the mtb tyres). A spoke was recently replaced and therefore the whole wheel was trued.
