Know before you buy
Yes. The Chorus 12-speed cassette is designed to match the width of an 11-speed cassette, so it is fully compatible with your existing 11-speed Campagnolo freehub body and frame spacing.
The two largest cog sets are integrated into a single block to increase stiffness. This design minimizes energy dispersion, ensuring more efficient power transfer when you are climbing or pushing hard in lower gears.
The cassette features the following tooth counts: 11-12-13-14-15-16-17-19-21-23-26-29. This provides a tight progression in the smaller cogs for precise cadence control, with larger jumps as you move into the climbing gears.
Yes, this cassette is engineered for use with a Campagnolo 12-speed drivetrain. For optimal shifting performance and longevity, you should pair it with a compatible 12-speed chain.
The special surface treatment is applied to reduce friction and increase wear resistance. This results in smoother, quieter shifting and helps the cassette maintain its performance over a longer lifespan.
