I've been having a few skipping issues with the cassette on my road bike. The 3rd and 4th largest ones. It's 10 speed record. The groupset hasn't got masses of miles on it, maybe 2/3k only used in the dry and taken good care of. The chain is just on .5 on the park stretched chain ometer, measured against a new chain, there's only 2mm in it over the length.
Has anyone else had a cassette where before the chains worn out? On my training bike I've changed the chain 3 times and still on the same cassette, which is a ti dura ace one. And it's done maybe 12/15k in any weather.
Bit miffed, as they ain't getting any cheaper.
