Cassettes/Freewheels

Prestacycle UniBlock PRO Cassettes are machined from a single solid block of cold-forged Chrome Molybdenum alloy steel, then heat-treated, tumble-finished and electroplated for added durability, low-friction operation and longer service life. The UniBlock PRO cassettes feature ARC™ shifting tooth profile technology that provides the fastest, smoothest possible shifting to all systems while minimizing the impact to power delivery. - Single block design offers 3D structure to optimize strength and distributes forces that allows Prestacycle to remove more unnecessary material making the ultra-light - Single block design ensures more freehub engagement by reducing torsional loads for less freehub wear and insuring the lowest rolling resistance within the freehub - ARC™ (Advanced Radial Curve™) Shifting Technology optimizes every single tooth pairing for exact-match pairings for both up-and-down shifts provide the highest possible speed and reliability in shifting... Even shifting under load is maximized - Compatible with all Campagnolo 9-12 speed freehubs, as well as N3W adapter kit - Wider inner and outer freehub teeth maintain engagement at all points in all gears and create an overall increase in freehub contact, no matter what gear you are in - Includes red anodized locknut

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 - For Shimano 12-Speed Drivetrains (NOT compatible with SRAM Road AXS or Campagnolo 12-Speed Systems) - ARC™ Maximum Performance 12 Speed Shifting - Red aluminum locknut included (For HG11 and HG12 freehub only) - Use on HG10 freehub requires Prestacycle HG10 lockring (Sold Separately)
