A fresh look at pulley design maximizing pulley size and improving pedaling performance for any derailleur
Redesigned shape of the pulley teeth now give better chain retention and accurate shifts every time
Updates to newest version include: Increased stiffness using A-Shaped pillars between the bearings and teeth, maximized tooth count for every derailleur helps deliver optimal drivetrain performance, and enhanced visual design achieves a more cohesive look across the different models
Road seal version runs with uber-efficient minimal contact seals to achieve the lowest friction
Cross seal versions are built for leaving the beaten path, offering the best durability, regardless of the weather conditions
