Prestacycle UniBlock PRO Cassette

The UniBlock PRO is designed exclusively for Campagnolo 10, 11, and 12-speed freehub bodies. It will not fit Shimano or SRAM HG-style hubs.

Because the cassette is machined from a single block of steel, it is incredibly rigid and resists the 'notching' that often occurs on aluminum freehub bodies with individual cogs. While this makes installation straightforward, it also means the entire unit must be replaced when the teeth eventually wear down, rather than swapping out individual cogs.

Yes, the ARC shifting technology is designed to be compatible with standard Campagnolo drivetrain systems. It is engineered to provide smooth, precise shifts without requiring any special proprietary derailleur.

With an 11-32t gear range, this cassette offers a versatile spread that is well-suited for hilly terrain and long climbs. It provides a low enough gear for steep ascents while maintaining a high enough gear for fast descents.

At 212 grams, this cassette is quite lightweight for a steel unit. By using a single-block design, Prestacycle removes the need for heavy spacers and carrier assemblies, resulting in a competitive weight that rivals many higher-end, multi-piece cassettes.
