TOKEN Shuriken Oversized Rear Deraileur Pulley System - Campagnolo EPS 12 speed

The Shuriken oversized pulley system was engineered for maximum performance and designed to increase the efficiency of the drivetrain on any bike. The larger diameter of the pulley allows the oversized pulley system to rotate at lower RPM and reduces the articulation angle of the chain, lowering drivetrain friction. The carbon fiber cage and hardened steel / dura-aluminum hardware creates a light and strong foundation for the system. The pulleys are made of dura-aluminum and PVD (Physical Vapor Deposition) coated for long-lasting low friction and clean aesthetics. A purpose-specified tooth profile ensures crisp shifting and super smooth running. Upgrading to the Shuriken oversized pulley system allows you to add drivetrain capacity to a short cage derailleur, enabling you to run a larger cassette with an expanded range of gears.  Specs: WEIGHT 69.5g / set COLOURS Matte Carbon PRODUCT CODE TK1739CE Cage plate: Carbon fiber Pulley wheel: 12T upper, 19T lower CNC AL7075 with PVD
