The updated low-profile "Shadow" design of the Shimano Ultegra R8050 rear derailleur increases its shift stability and gives it a sleek and integrated appearance. Race endurance is guaranteed, through the optimised slant angle. The wide cassette compatibility of 11-25 tooth to 11-30 tooth will secure a smooth ride in even the highest and steepest mountain areas.
Every particular has been designed down to the smallest detail to obtain the maximum effectiveness. The Record rear derailleur ensures rapidity and precision in every situation. Available with a short or medium cage, to interface perfectly with classic and compact cranksets.
With its compact and smooth appearance, the Shimano Dura-Ace Di2 front derailleur delivers quick and smooth front shifting even under high pedalling torque. Plus, it has programmed chain guide trim settings and can be used in full or semi Shimano Synchronised Shift modes to bring you a personalised, top-level shifting experience. Shimano's 9150 groupset brings its Syncro-Shift technology to the road too. Syncro-Shift technology enables the Shimano Dura-Ace Di2 R9150 front derailleur to read the position of your Di2 rear derailleur and will automatically operate the front shift to position the gears in the most efficient gear and best chain line, so you'll never have to worry about front shifting and correction shifts again.
The Campagnolo Chorus EPS groupset takes a great deal of its DNA from its mechanical counterpart as it represents a more accessible version of Campagnolo performance, quality and attention to detail but delivers it in the laser-like precision package of an EPS drivetrain. The shifting performance of the Chorus EPS groupset is exactly the same as its lighter weight siblings, Record and Super Record, making for a transmission fit for professional racing. Shifting even under heavy load is no problem for the Chorus EPS transmission and mud, grime and debris have met their match against such powerful motors. The EPS rear derailleur is comprised mainly of a mechanical structure, derived from the mechanical gear and composed of a derailleur rod/parallelogram/derailleur cage, of a worm screw enabled by an electronic actuator. As with the derailleur, the electronic rear derailleur actuator is composed of a gear motor and a sensor, the built-in resolver, that reads its movements. The geometry of the parallelogram has been made more rigid and optimised to promote interaction with the electronic parts. The rear derailleur is also equipped with a play recovery system using a helicoidal spring that optimises stability and precision and keeps operation and performance constant over time, even after many kms have been covered. As with the mechanical rear derailleur, it is possible to optimise its position with respect to the frame and chain by acting on two adjusting screws: the screw that adjusts the mechanical end stop and the screw that adjusts the distance between the upper pulley and sprockets. By using these screws it is possible to optimise the installation of the rear derailleur and increase the precision of its operation. DTI: Digital Tech Intelligence is housed inside the Power Unit and it continuously monitors the signals that arrive from all the EPS components, thus managing their operation. Multi-Shifting There are no longer any limits to multi-shifting and the choice is at the fingertips of the cyclist. Ride back home The uncoupling mechanism of the rear derailleur is useful if the battery runs out ""on the road"", allowing you to manually ""uncouple"" the rear derailleur to position it on which ever sprocket you require. Waterproof In order to achieve the IP67 classification, all the electronic components of the EPS system underwent a series of tests, which proved their ability to function perfectly under one meter of water for at least 30 minutes.
The derailleur is designed with our Exact Actuation technology for precise, efficient shifting. We have paid special 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 rear Derailleur smoother and quieter than ever before.
Part of SRAM's high-performance AXS ecosystem, this rear derailleur is faster, more consistent, and lets you shift when you want, even under load, without having to plan around the terrain.

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
