The SRAM Rival eTap AXS wide front derailleur is optimized for smaller X-Range chainrings on wide cranks and uses Yaw technology so there’s no need for trim. Its wider position on the bike also provides clearance for extra wide tires, so you can venture far beyond the beaten path.With a front derailleur cage that rotates to maintain a consistent angular relationship with the chain, yaw technology eliminates the need for shifter trim. As a result, shifts feel more direct and precise, delivering an unmatched performance advantage in front shifting.AXS is as you know Sram\'s new bike component integration system that connects electronic bicycle components and software.
