Bicycle Cassettes & UniBlock™ Drive Systems

Industrial Innovation

Single-Piece Cold-Forged Steel Architecture

In high-performance road, gravel, and mountain bike drivetrains, saving weight has traditionally meant sacrificing component lifespan by using soft aluminum alloys. Prestacycle UniBlock™ technology completely transforms cassette performance by engineering a single solid block of high-tensile cold-forged steel into a unified 3D structure.

Because every cog provides continuous structural support to neighboring gears, UniBlock™ cassettes eliminate material waste, drop weight below conventional multi-piece aluminum-spider cassettes, and significantly increase wear resistance against extreme chain load. Engineered for professional racing teams and global distributors seeking low-return, high-margin drivetrain solutions.

FAQ

Frequently Asked Questions

Essential technical and commercial information regarding Prestacycle UniBlock cassettes.

Why are Prestacycle UniBlock cassettes longer-lasting than standard alloy cassettes?

Prestacycle UniBlock cassettes are CNC-machined from a single solid block of high-tensile cold-forged steel rather than soft aluminum alloy. Because every cog supports the surrounding structure in a 3D architecture, we can reduce overall material mass while ensuring the steel teeth withstand thousands of extreme shifting stress cycles.

Are UniBlock cassettes compatible with standard Shimano, SRAM, and Campagnolo drivetrains?

Yes. UniBlock PRO cassettes offer exact tooth spacing and ramp profiles engineered to work seamlessly with Shimano HG11/HG12, SRAM XDR, and Campagnolo freehub bodies using dedicated UniBlock lockrings and adapters.

Do UniBlock cassettes dig into soft aluminum freehub bodies?

No. Unlike traditional loose individual cogs or multi-spider designs that concentrate chain force onto individual splines, the single-piece 3D base of the UniBlock cassette distributes torque across the entire spline surface, completely preventing freehub gouging.

Does Prestacycle offer wholesale B2B pricing and global shipping for dealers?
