Ready to conquer the challenges associated with road cycling, this rear derailleur is equipped with a tough aluminium build and wireless technologies for greater precision, customisation and control wherever your road bike takes you. Its durable aluminium construction makes it more than capable of handling the changes to the terrain conditions and the consistent gearing that comes with it on your travels. SRAM has also kitted out this model with high-quality steel pulley bearings and larger X-Sync pulleys, so riders can enjoy increased strength and efficiency. Another benefit is its Orbit chain management technology, which makes shifting easier and quieter as you clock up the miles. Road Bike Rear Derailleur with AXS Wireless Connectivity 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 Force 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 - Orbit chain management technology keeps the drivetrain quiet and secure - 1x specific for use with 10-44 XPLR and 10-36 cassettes - SRAM AXS enabled, allowing easy personalisation - 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. Orbit: Orbit technology is an innovative form of derailleur motion control. It utilises silicon fluid as part of an elegant and ultra-lightweight damper system. Compared to a standard friction clutch system, Orbit technology places no additional resistance on the rear derailleur’s spring when under slow or light movement. This means easier shifting and rear wheel removal. And while riding, the fluid damper reduces chain bounce. Manufacturer's Part Number: 00.7518.158.000
The Oversized Pulley Wheel System for SRAM Rival AXS features a 15-tooth upper and 19-tooth lower pulley wheel setting, for maximum efficiency. The handbuilt OSPW System has two spring tension settings, that allow customised setup based on riding conditions. As with all other CeramicSpeed products, this new OSPW System has been thoroughly tested. Besides thousands of test kilometres among both professional and amateur riders, CeramicSpeed's Founder and CEO has spent more than 5.000 km in the saddle, testing the product. With the guys from R&D following him closely and listening to his feedback from every single ride, we can proudly say that no details are left un-tested. Since its introduction in 2015, the CeramicSpeed Oversized Pulley Wheel System has been through 13 unique derailleur compatibility developments. No other pulley system has the depth of use and trust as the CeramicSpeed OSPW, which counts both Men’s and Women’s Triathlon World Champions, World Tour professional road teams, XCO professional MTB Teams, and elite athletes worldwide as its users. The aluminium CeramicSpeed pulleys come in both coated and standard versions (see multiple options in the selection menu at the top).
Dura Ace Di2 9150 Front Gear Braze-On - 11 SpeedElite road racers demand reliable and precise shifting, 11-speed Dura-Ace R9150 delivers with its super-lightweight yet durable designSynchronized Shift designed, developed to choose the next biggest or lowest gear ratio irrespective of whether a gear change needs to be made by the front or rear derailleurThe Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleurThe biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under loadThe difference in the effort and time to actuate the shift between mechanical and Di2 is truly staggeringThe removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shiftsThe front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road aheadBraze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available11-speed E-tube Di2 compatibleCompatible with 50-55 tooth chainringsTotal capacity 16TFront derailleur weight is 104 grams
SRAM have also paid attention to the finer details, like adding a hollow titanium anchor bolt and even refining tooth geometry of the jockey wheel. The result is that the chain runs through the new RED Rear Derailleur smoother and quieter than ever before.
SRAM Red WiFLi 10sp Rear DerailleurThe SRAM RED Rear Derailleur has been designed to deliver the performance advantage you‘ve come to expect from SRAM.
