Key Features
- Rugged Material & Superior Rust Protection ：Crafted from high-rigidity solid steel, it delivers great impact resistance and withstands high torque during intense riding without deformation or wear. The surface is treated with 3-layer nickel-chromium electroplating to form a dense protective coating. It offers excellent waterproof and anti-rust performance, ensuring long service life even in rainy and humid conditions.
- Professional Cassette Structure ：Built with a standard cassette design, it fits most common wheel hubs and installs easily. Equipped with a lock ring (torque specification: 40N·m), it stays firmly secured without rattling while riding. The sprockets are precision stamped with optimized tooth profiles for smooth chain engagement, effectively preventing chain skip and drop for stable gear changes.
- Wide Gear Range & Great Compatibility： It features a minimum gear of 11T. The wide gear ratio balances effortless climbing and high-speed riding on flat roads. It is fully compatible with major groupsets such as SHIMANO and SRAM.
- Lightweight & Optimized Structure： Hollowed sprocket design reduces overall weight while retaining structural strength, lowering drivetrain resistance for better acceleration and a lighter riding feel. The optimized sprocket layout ensures seamless chain transition between gears, eliminating shifting lag and delivering accurate, fluid gear changes.
