Prestacycle UniBlock 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. The 2 largest cogs on the 11-40 and 11-42 HG11 cassettes are crafted with one-piece of high quality 7075 aluminum.

- Red aluminum locknut included (For HG11 and HG12 freehub only)
- Use on HG10 freehub requires Prestacycle HG10 lockring (Sold Separately)
- Single block design allows Prestacycle to remove more unnecessary material, making cassettes lightweight and easier to clean
- Shifting ramps and profiled teeth provide smooth and consistent shifts
- Honeycomb design allows for maximum material removal while maintaining strength
- Designed to last longer than standard steel cassettes
