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 ?

What do you mean by "backlash on the wheel"? – Daniel R Hicks Aug 18 '13 at 19:30
the cassette has a little play on the rear hub – Abrahamyan Samvel Aug 19 '13 at 7:48
THAT should not happen. If the cassette is already fairly tight, check whether the cassette is even compatible with the freewheel. – arne Aug 19 '13 at 10:05
It sounds like the cassette is falling apart, or has been misthreaded. – Daniel R Hicks Aug 19 '13 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. – Kaz Aug 21 '13 at 0:06

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 .

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:
