Prestacycle UniBlock PRO Cassette - 12-Speed Shimano For HG 12 Freehub 11-30 Silver. 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.
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
