There is only one part that may actually lasts longer and that is the BB bearings. The CULT bearings are unlike any other ceramic bearing used on bikes and only require oil for lubrication. If you buy Chorus and wear out the bearings, they can be replaced with SR bearings, later.

There is also one ceramic ball bearing on the lower jockey pulley, compared to Record that has two ceramic bushings and Chorus that has two standard bronze bushings. The ceramics are intended to reduce friction more than increase life.

The SR parts cost a lot more and shave very few grams from the total weight. Chorus is a far better deal. You can buy the whole group for about $1100 from Ribble. The SR group costs $1960. It's not worth $860 more. The Record group isn't worth over $500 more, either. It used to be more like $300 more, which was tolerable.

There is no reason you should have to accept all SR parts; you can mix and match as you please. I never buy anything but Chorus cassettes because they cost about 1/3 as much as SR and last twice as long.

Dave is right on track here. I purchased Chorus 11 because it was $800 and change less than SR. And yes, when the jump was perhaps $300, no as big a deal. But the $500 for Record and $800+ for SR is probably money not wisely spend. If you have the budget, put it into better wheels.

Let's see some pics after you are done.

How many miles are you guys getting out of your Chorus 11 cassettes/chains?

Athena!

If money is not an object get SR11 and change the cassette as it wears. Otherwise money is an object.

SR11 rides beautifully, but probably so does the whole 11 set.

Cassette and chain mileage is a whole different topic and quite complicated, since Campy chains don't wear like most other brands and most people have no clue how to measure the wear properly. Riding conditions and maintenance technique all have major affects on chain life.

I once use a Campy 10 chain for 6,000 miles before it was totally shot. I expect less from the new 11 speed chains, but at least 4,000 miles. Some riders will get more if they ride flatter terrain that's not as gritty as the roads I'm on. One person on another site posted an increase in roller spacing of only .015 inch and no mesureable elongation (with a 12" scale) after 2500 miles. Even though he weighs 40 lbs more than I do and we both use the same homebrew lube, he's getting less wear than I'm seeing. I'll trash a Campy chain when the roller spacing increases by about .040 inch, regardless of how small the elongation is. You can't leave a single chain in use for that long without risking new-chain skip, when a new chain is installed. I use a 3-chain rotation and never let a chain become more than half-worn before switching to the next one. I expect no less than 12,000 miles from 3 chains and one cassette. With 10 speed, I'd expect 15,000.

The cog thickness is the same as Shimano 10, so the cogs should last just at long.

I agree with Angry Sci - get the full SR group, and replace the cassette in 20k miles. Or, get the whole group, and SELL the expensive SR cassette, and buy 2 Chorus cassettes!

Either way, no matter how much value you lose by getting SR, nobody will ever stop you and say "you should have got Chorus on that bike"!
