• SRAM’s DH specific derailleur is designed to provide fast and precise shifts for the close ratio cassettes used on DH race bikes, 4X and jump bikes.
• X-HORIZON architecture provides more responsive shifting
• X-ACTUATION with more cable pull provides better system performance and durability
• X-HORIZON eliminates ghost shifting, very commonly found on DH bikes
• EXACT ACTUATION (MTB 10-speed) variant allows upgrade to existing bikes in the aftermarket
• X-SYNC: A CNC-machined, “wide tooth, narrow tooth” pattern is repeated around the entire XX1 chainring, perfectly mirroring the 1X11 XX1 specific chain’s inner and outer links for maximum control
• ROLLER BEARING CLUTCH: Designed for X0 and X9 families, Type 2.1 rear derailleur delivers maximum drivetrain stability—even through the most punishing technical terrain. With Roller Bearing Clutch™ technology, SRAM Type 2.1 eliminates derailleur bounce and chain slap without sacrificing precision
