Every tooth of each sprocket is meticulously designed to ensure top - notch synchronization, rapid shifting, and quiet operation. The six larger sprockets feature a double - frame system, providing outstanding torsional stiffness. This means that even when shifting under pressure, the operating precision remains intact. The surface treatment of the eleven steel sprockets not only extends the component's lifespan but also ensures consistent high - level performance over time. Specification: It's an 11 - Speed cassette only. The ULTRA - SHIFT TEETH DESIGN means each sprocket tooth is carefully placed to perform specific functions like lifting or lowering the chain and delivering maximum power to the wheel. The NICKEL - CHROME SURFACE TREATMENT reduces the friction between the chain and sprocket, significantly increasing the sprocket's longevity.

Using this Campagnolo Chorus 11 - Speed Cassette is easy. Just install it on your bike's compatible hub as you would with any regular cassette. When shifting gears, use your bike's shifters smoothly to move the chain across the sprockets. Make sure to apply appropriate pressure when pedaling during shifting to ensure a seamless transition. As for maintenance, keep the cassette clean by regularly wiping it with a dry cloth to remove dirt and debris. You can also use a mild bike cleaner for a more thorough clean every few months. Avoid using harsh chemicals as they may damage the nickel - chrome surface treatment. Check the sprockets periodically for signs of wear. If you notice excessive wear or rough edges, it might be time to replace the cassette.
