Product Description

The Shuriken oversized pulley system was engineered for maximum performance and designed to enhance drivetrain efficiency on any bike. The larger pulley diameter enables the system to rotate at lower RPMs, reducing the chain's articulation angle and subsequently minimizing drivetrain friction. The TBT bearings within the pulleys are filled with specially developed light grease to keep drag low and minimize resistance. The combination of a carbon fibre cage and hardened steel/dura-aluminium hardware establishes a lightweight yet robust foundation for the system. The pulleys themselves are crafted from dura-aluminium and coated with PVD (Physical Vapor Deposition) for enduring low friction and a clean aesthetic. A purpose-specific tooth profile ensures precise shifting and exceptionally smooth operation. Upgrading to the Shuriken oversized pulley system not only allows you to increase drivetrain capacity on a short-cage derailleur but also enables the use of a larger cassette for an expanded gear range. Embrace a more effortless and enduring ride with the Shuriken oversized pulley system. Conti-Wave Conti-Wave machining reduces chain noise as it minimizes the contact surface against the chain. EOM Eccentric Orbital Motion in the upper pulley ensures compatibility with the original drivetrain and enhances shifting in higher gears.
