Cassettes

The Prestacycle UniBlock Pro Cassette redefines performance with innovative engineering. Unlike traditional lightweight cassettes that sacrifice durability, UniBlock uses stronger steel—allowing us to reduce material while maintaining strength. Our unique 3D structure ensures all cogs support each other, making the cassette lighter without compromising longevity. Plus, with its single-piece design, installation, removal, and cleaning are effortless—no risk of misaligned cogs. Lighter, longer-lasting, and easier to maintain, the UniBlock Pro Cassette is built to help you Start Your Ride Faster.
