Mileage on Campy Chorus Cassettes

[Lookbiker]

Hi,
I know that it varies considerably but what are you averaging for mileage before replacing the cassette?

Thanks

I use Centaur cassettes (no advantages to higher level cassettes) and get about 20K miles on them. But as you point out there are a LOT of variables so you will not really learn anything from the responses you get to your question.

My record keeping stinks but to me my record and chorus cassettes get better mileage, appear to be more finished (what ever that means) and shift smoother than the lower level lines, however I must admit it might be due perception only. Also that fraction of a pound weight savings could possibly be important to me in rocketing away from a stop or climbing a mean incline.

Eh, was OP talking about Chorus 10 or 11?

[Lookbiker]

Using Chorus 11.

You can get 20k+ miles from them, *if* you are diligent about measuring the chain and replacing it when it is stretched even a little, and cleaning and lubing and wiping off the chain. As the chains stretch they will wear the teeth to a sharp point, when that happens the cassette and likely the chainrings are done. Also, sand/dirt in the excess oil on the chain accelerates this process. Lastly, keep everything adjusted well, driveline noises are bad for cassette life.

I tend to get 3 to 4 chains worth out of each cassette.

depends on how often you clean / change your chain honestly

When comparing Veloce' and Record cassettes, I find no difference in shifting or noise. The Record cassettes certainly do wear out faster (assuming you spend significant time on the Ti cogs). YMMV

+1.

That's somewhere around 15,000km. I live where there are big mountain with lots of climbing and lots of rain (seasonal).
