Recently I have bought a used 2012 Cube CLS LTD PRO hybrid bike in a good condition . The only thing was the rear cassette a little wobbling. I asked a mechanic about this and he told that almost every bike has this problem . After riding about 300 km I noticed that the cassette is wobbling more than it had been. Today I took the rear wheel off and saw that the cassette had a tiny backlash on the wheel . Can I fix the wobble simply by tightening the cassette , or should I buy a new one ?

    THAT should not happen. If the cassette is already fairly tight, check whether the cassette is even compatible with the freewheel.

    It sounds like the cassette is falling apart, or has been misthreaded. Aug 19, 2013 at 11:09
  • "backlash" refers to "gear backlash": which is a jerking effect caused by free play in a moving transmission; it is not a synonym for free play itself.

Wobbling cassettes should be absent from, not present on, every bike. It is possible that the wobble is caused by worn splines on what might be a soft (aluminium, as opposed to steel) freehub. I myself recently blogged about such an issue at http://bit.ly/HubTrouble .

The wobble might instead be a result of an incorrectly seated lock-ring, or a missing spacer from behind the cassette (in which case you might find this link of interest: http://bit.ly/CassetteIssues)
