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.
- 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
- 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
