A clean chain shifting crisply across a new cassette sounds like a finely tuned choral performance, to certain ears, which means the smooth, confidence-inspiring Campagnolo Chorus 11 Cassette is the Vienna Boys Choir of bike components. That's not to say that it'll cost as much as a trip to Austria; while the Chorus 11 features the same tooth shaping, spacing, and Ultra Shift technology as Campagnolo's titanium Super Record 11 and Record 11, it's made of chrome-plated steel, which saves you a significant chunk of change. Steel's more durable too, so the Chorus 11 will last longer than either of the other two, and it adds only a minimal amount of weight—56g more than the Super Record—so it's perfect for all but the weeniest of weight weenies. As the finishing touch, Campagnolo employs a lightweight alloy lockring that holds it all together.

Thousands of miles of service
- I've put it through the wringer
Built my Cervelo RS with Chorus 11-speed in 2009 with a 12-25 Chorus cassette. Perfect shifting from day one. The only time shifting got out of whack was after my bike got dropped and the derailleur hanger bent. New hanger solved that problem. Love the 'chink, chink' of downshifts under load.

Works great for me!
Just took a test ride on my newly installed Super Record 11 using a Chorus 11-25 cassette. I don't have any complaints. Maybe I'm prejudiced since I've been riding Record 10 for the last 6 years (btw, it's not worn out, just going on another bike for my son. It's only got 45,000 miles on it). The new cassette design really does shift quickly too! Now I'm going to REALLY have a hard time trying to make my friends' Shimano and SRAM systems shift as nicely as mine! Of course, I did used to own a Campy Pro Shop, I know how to set Campy up. Remember, there's more to making things work correctly than just bolting the components on. The derailleur hanger has to be straight and true, limits adjusted properly, cables need to be clean and free traveling, etc. I can't count how many times I've had to correct the work done by bike shops AND Shimano neutral support. (Remember Mara Abbot's issue at the 2013 National Championships in TN where they broke her derailleur off trying to change her rear wheel?) Installed this cassette on a HED JET 6 FR rear wheel. No issues. In this case it was bolt it and go!

I have about 100 miles on a just installed Chorus 11-25 11-speed cassette. So far the shifting is excellent, noticeably improved over the Chorus 10 cassette. It seems to work just fine with a Record 10 rear derailler. Beware when installing it on any other hub than a Record hub as the hub may require a modification (Zipp, Rolf, are two I know of). The cassette does come with a variable assortment of spacers requiring more care during install. The smallest cog does just barely grab the end of the freehub, but seems solid when locked down with the lockring. It just looks odd though.

If you leave the cassette on the plastic holder and use the it to slip the whole cassette on at once you never have to deal with any spacers.

Campy Chorus 11 cassette problem
I had the full Campy Chorus 11 component group installed on my Litespeed Tuscany frame in mid-June 2009. It did not work properly from the very first shift. Specifically: when I attempt to shift from the 18 cog to the 19, it just sits in the 18 and clatters. My bike shop called Campy and they sent them a replacement part they called an "indexing plate". It took 6 weeks to get that part. After it was installed, the problem was still there. In frustration, I finally called Campy myself and they told me there's a problem with a spacer in the 12-25 cassette (which is the one I have). They're sending the new spacer to my LBS, and they're going to send it to me to put on (I live over an hour away from the shop). My LBS called Campy, too, and they told them that there's no problem with the 12-25 cassette, it's the 11-23 that has the problem. Bottom line: I put a lot of money into a component group that doesn't shift properly, and I'm getting mixed messages about why. It's been over 2 months now, and I'm an unhappy camper.

I had a Campy 10 speed drivtrain which consistently skipped the 18 cog when riding. The chain would shift fine when the bike was on the stand, but with a rider aboard it would always skip 18 to 19 from 17. Local bike shop which sells lots of Campy stuff testrode it and said the exact same thin happened to them. Never got resolved and I sold the group on ebay, got SRAM and never looked back. I think Campy is the most overpriced, overated crap out there. Shifts are clunky, not smooth, hubs are hard to come by, they dont even make silver hubs anymore, everything is now an ugly black and even their cranks look like crap with all that carbon and no silver.
