UniBlock PRO Cassette - 12-Speed For Campagnolo 9-12 Speed Freehub

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 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
