Pro and durable.
The Campagnolo Chorus 11 Cassette is built on the same Ultra Shift platform, with every bit of applicable technology, as the Record 11 and Super Record 11 cassettes you see in the pro peloton. The legendary cog tooth synchronization, shaping, and spacing — they're all here. The only difference is that Record and Super Record incorporate either three (Record) or six (Super Record) titanium cogs in their cassettes. This means they save 29 and 53 grams over Chorus, respectively. But titanium is also softer than the nickle-chrome coated steel used in the entire Chorus cassette, so the cogs will wear more quickly.
If you've been reading up on the 2015 models of Campagnolo's top-end components, then you know that there are compatibility issues between them and previous iterations. The cassette is the one exception to this rule on the drivetrain. All Campagnolo 11-speed cassettes work perfectly with all Campagnolo 11-speed shifters and derailleurs.
The Campagnolo Chorus 11 Cassette comes with a lightweight alloy lockring.
- Steel cogs on an alloy carrier
- Alloy lockring included
- Chorus cassettes compatible with all iterations of Campagnolo 11-speed drivetrains, even the most recent
