*Fully compatible with XX SL, XX, XO Eagle AXS Transmission and SRAM Eagle 90 Transmission (Not compatible with GX systems). With our FURTHER DRIVE Technology – comprised of two new technological features, both aimed at ensuring the OSPW X enhances the Transmission group's ability to maintain efficient performance over time. Active Debris Remover (ADR) Feature - a new exclusive dust wiper design that securely anchors into a recess in the pulley, thus fully enclosing the bearing. This is paired with a lamellar groove structure that surrounds the dust wiper and dynamically extracts debris from the pulley as it rotates. The ADR is paired with our new solid disc 14 and 20 tooth pulleys, simply known as ALPHA. The ALPHA Disc features a two-piece construction. A separate narrow-wide tooth profile, made from composite material offering extended wear protection and noise reduction. Plus a solid aluminum disc that eliminates the possibility of foreign objects getting caught between the pulley spokes, while adding strength and rigidity to the Pulley design. FURTHER DRIVE Technology is combined with a completely new cage structure that uses a reinforced material structure – without adding unnecessary bulk – making it perfectly in line with the robustness for which the Eagle Transmission group is celebrated. But the real value lies in FURTHER DRIVE Technology's ability to deliver peak performance deep into races or the season, when riders need it most. Faster now and faster in the future – Test of Time. Note: although the cage mounting interface is visually the same between SRAM Transmission derailleurs and the new 13-speed SRAM RED XPLR derailleur, the pulley positioning and cage rotation are different, and we do not support the use of this cage on any XPLR derailleur.
