Providing the precision and reliability of 12 speed eTap AXS at a whole new level, this rear derailleur is designed to tackle every road surface you can imagine. It features a tough aluminium cage construction, which makes it suitable at handling the demands associated with clocking up the miles on your road bike. Coming equipped with high-quality steel pulley bearings and larger X-Sync pulleys, SRAM has engineered this model for increased durability and efficiency wherever your ride takes you. Another highlight is its secure chain management set-up, which delivers fast and precise shifting as well as a smoother and quieter ride. AXS Enabled Road Bike Rear Derailleur If your ride doesn’t feel complete until you get a little dirt on your tyres, you know the importance of capable components that can tackle anything. The Rival XPLR eTap AXS rear derailleur is a dedicated 1x-specific unit designed for use with the XPLR 10-44 cassette. It makes for an uncluttered drivetrain that takes on pavement and singletrack with equal assurance. Wireless and proven eTap shift logic, AXS connectivity and advanced chain management mean this derailleur does exactly what you want when you need it. - Wireless electronic eTap shift logic for intuitive shifting, easy setup and reliability - 1x specific for use with 10-44 XPLR and 10-36 cassettes - SRAM AXS enabled, allowing easy personalisation - Chain management keeps the drivetrain quiet and secure - Larger X-SYNC pulleys for increased durability and efficiency - Compatible with existing eTap batteries Technologies: AXS Enabled: AXS is SRAM’s bike component integration system that connects electronic bicycle components and software. Control: AXS lets you connect your AXS-enabled components to a mobile app, where you can assign custom actions to your controls. Everything speaks the same language, and you can even combine road and mountain bike parts to build the party bike of your dreams. Personalise: Wireless controls open the door to new levels of customisation. With AXS, you can personalise your component behavior to match your riding style and preferences. Turn on enhanced shifting modes, or reassign shifting actions. Measure: The AXP Mobile App and AXS Web allow you to monitor your bike’s performance and readiness. It’s an easy way to keep tabs on your battery levels—including the CR2032 batteries in eTap shift levers—and keep AXS component firmware up-to-date. AXS Web analyses your ride files specific to shifting, gear use, power zones, and tyre pressure, so that you can quickly and easily learn more about how your bike is working for you and consider adjustments. X-Sync: SRAM X-SYNC chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle-shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation. Manufacturer's Part Number: 00.7518.159.000

SRAM X01 Type 2.1 11 Speed Rear DerailleurThanks to its “horizontal parallelogram” design, X-HORIZON can keep the chain gap the same across all 11 gears. By taking vertical movement out of the equation, this design doesn’t just make shifting faster—it reduces shift force and eliminates ghost shifting.Features: Cage Lock: The first rear derailleur of its kind, SRAM Type 2.1 lets you push your cage forward and lock it into place with the push of a button. This creates slack, removing all tension from the chain. With Cage Lock, Type 2.1 makes wheel removal and installation—as well as chain installation—easier than any other derailleur on earth. Just push the cage forward—creating slack—and lock it in place. The chainstays perfectly loose, letting the derailleur swing out of the way. When you’re ready to ride again, simply unlock the cage and go Roller Bearing Clutch: Designed for X0 and X9 families, the Roller Bearing Clutch eliminates derailleur bounce and chain slap without sacrificing precision. The maintenance free clutch design accurately controls chain tension and creates smooth, reliable performance and consistent shifting accuracy. X-Actuation: Developed specifically for SRAM XX1, X-ACTUATION keeps shifting sharp and consistent across the entyre 10-42T cassette X-Horizon: This XX1 rear derailleur’s “straight parallelogram” design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a consistent chain gap across all gears X-Sync: A CNC-machined, “wide tooth, narrow tooth” pattern is repeated around the entyre XX1 chainring, perfectly mirroring the 1X11 XX1 specific chain’s inner and outer links for maximum controlSpecifications: Speeds: 11-speed Material: Inner Cage: Alloy; Outer Cage: Carbon Fibre Weight: 252g Compatibility: 1X11 Capacity: 32T Pulleys: 12-tooth X-SYNC pulley wheelsBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
