Unique one-piece crmo steel cassettes

SHIMANO / SRAM - 25 to 34T

lighter and more durable than the competition

  • One-Piece MonoBlock™ Design

    Each MonoBlock is machined from a solid block of chromolybdenum steel. This allows for an optimized 3D design instead of single cogs pressed together. Resulting in a stiffer and lighter construction.

  • Electroplated CrMo

    CrMo steel is significantly harder than Aluminium which is often used in high-end cassettes from the top drivetrain brands. The steel Monoblocks will last longer.

    Our Monoblocks are heat-treated, tumble-finished and electroplated for added durability and a low-friction operation.

  • Reliable Shifting

    Improved profile designs for the teeth. Adapted to the cogs next to it.

    The one-piece cassette has also a solid connection with the freehub, which avoids any movement of the cogs in relation to the derailleur and chain.
