Prestacycle UniBlock Cassettes Cassettes are a single-piece unit exquisitely machined from a solid block of cold-forged Chrome Molybdenum alloy steel, then heat-treated, tumble-finished and electroplated for added durability and low-friction operation. They are designed to last longer than standard steel cassettes.
- Single block design allows Prestacycle to remove more unnecessary material, making cassettes lightweight
- Easier to clean
- Shifting ramps and profiled teeth provide smooth and consistent shifts
- Honeycomb design allows for maximum material removal while maintaining strength
