I use Chorus 11 speed cassettes on an otherwise Super Record group set. In my experience, they last much longer than the Ti Record and SR cassettes.

I've only ever used Chorus cassettes (and Record chains), so I'm repeating what I've heard from others. And what I've heard is: "twice to 3 times as long"

Utter nonsense. With Super Record cassettes, the largest six cogs are titanium. The first five cogs are STEEL. With Record cassettes, the largest three cogs are titanium. The first eight cogs are STEEL. In the charts below the titanium cogs are after the "Ti".

On all my nine and ten speed bikes I spend 99% of my time in the 13-14-15-16-17 cogs. So only with Super Record would I ever use any titanium cogs. For me, and I suspect many many others, Chorus, Record, and Supr Record cassettes would last exactly the same. Maybe Super Record would last 10% less. If you never ever use a cog, it will last forever. Titanium cogs are only put in parts of the cassette that rarely ever see any use.

I run an 11-29 and have always gone to SR when the price is right and weight is a major concern. On my Neo I am using 11-29 chorus cassette as the weight benefit is irrelevant.

:lol:

Saying Ti cogs last just as long as steel ones because they don't get used anyway is non sequitur. When addressing the question of wear and longevity, the starting point must be that the cogs in question are equally used.

Anyway - this is the Internet, so :thumbup:

But they’re not equally used... I’ve found that on my Record cassettes, the smaller 15-17 cog are the fastest wearing and the limiter in terms of cassette life, not the Ti cogs. So I guess for me, Chorus and Record cassettes last the same amount of time.

I suppose that'd make sense if you'd then go and buy individual/separate cogs to extend the life of a cassette.

How many actually do that? Campy pricing seems to dictate that spare cogs on their own cost 2/3 of the cost of a whole cassette. And what happens when you have uneven wear across the cassette? How do you track wear on individual cogs? All seems a bit silly for a miniscule weight saving.
