10 speed Tiagra to 105 / Ultegra

[wam68]

I am gonna change the cassette on my winter bike which carries a complete Tiagra groupset. Nice enough, all thing considered but a bit long in the tooth. The 105 / Ultegra 10 speed cassettes are well priced at the minute so I am going to go for one of them. Can anyone see a problem going for the 105 / Ultegra cassette and taking out the Tiagra cassette. Something in my mind says that the chain may have to go as well.

No problem at all. You may need a new chain depending how worn the cassette is.

Is the cassette worn? If not then there's no need to change. If it is then you will also need to change the chain.

For the sake of £10(or whatever it is) do it right and change the chain too.

I wouldn't be able to sleep if I'd cheated like that. Can't change a tyre without changing tube too

Thanks everybody. New cassette and chain it is then.

Just don't get a Shimano chain, they are pants.

What's the gear changing like with the KMC. Is it just as smooth. I know they are longer lasting but is their a big difference in the smoothness of the changing. Cheers

No discernible difference.

Buttery smooth.

KMC all the way.

You probably won't detect any difference between Tiagra cassette and Ultegra cassette, your wallet might though, Tiagra cassettes can be had for £12.50
