Prestacycle UniBlock PRO Cassette

Yes, this cassette is specifically engineered for compatibility with Shimano 12-speed drivetrain systems.

The single-piece design eliminates the need for individual cog spacers, which simplifies installation and prevents the cassette from digging into your freehub body. Because it is machined from a solid block of cold-forged Chrome Molybdenum steel, it offers exceptional durability and resists the wear typically seen in multi-piece cassettes.

The honeycomb structure allows Prestacycle to remove excess material from the cassette body, significantly reducing weight without sacrificing the structural integrity or stiffness required for crisp shifting.

Yes, a lockring is included with the cassette, so you have everything you need for installation right out of the box.

ARC shifting ramps are specifically profiled to guide the chain onto the next cog more efficiently. This results in smoother, more consistent gear changes, even when you are under load.

The largest cogs are crafted from high-quality 7075 aluminum to keep the overall weight of the cassette as low as possible. Since these larger cogs experience less torque-related wear than the smaller ones, aluminum provides the perfect balance of weight savings and longevity.
