The absolute pinnacle of gravity drivetrains. Period. Leveraging SRAM's Hangerless Interface, the SRAM XX DH Transmission (RD-XX-DHE-A1) Derailleur evolves the proven T-Type architecture into a dedicated downhill weapon, heavily fortified with replaceable skid plates and a rebuildable cage to survive World Cup rock gardens and massive freeride hits. Wireless AXS integration guarantees surgical shifting precision and a zero-clutter cockpit. Crucially, the derailleur and cassette communicate flawlessly via Cassette Mapping, maintaining constant chain engagement for seamless power transfer under maximum load. The result? You can dump gears while sprinting out of the start hut or hammering to the finish line, with zero hesitation and zero compromise.
