Durable performance

A performance upgrade for SRAM XX1, X01, X1 Drivetrains - They are precision CNC'd from special Thermoplastic that have excellent stiffness, high hardness rating, structural stability and produce very low amounts of friction. This makes them very quiet, durable and smooth running and exceptional in muddy conditions.  Super light at only 5.2g per pair, they reduce drivetrain noise and immediately improve shifting - especially if your pulleys are worn. Rebuildable double sealed bearings, a worthwhile upgrade with lots of performance-per-dollar. Perfectly machined, very good looking and one of the lightest on the market

• Sold in pairs
