The Chorus cassette is the workhorse cassette of the Campagnolo line-up. Many Campy riders choose the Chorus cassette because it is almost as light as the higher-end Record 11 cassette but is almost half the price. This is due to the fact that they do not sport the titanium cogs that the Record does. All cassette cogs feature the Ultra Shift® cog profiling with drilled and scalloped upper cogs for reduced weight savings and improved shifting. All cogs rest an alloy carrier that reduces both weight and wear on the freehub body of the hub.
