BATTERY NOT INCLUDED Lighter, faster, and more capable than ever, the Force AXS rear derailleur does it all in style. Covering cassette ranges from 10-28T up to 10-36T, this wireless wonder has a new, lighter cage and a larger pulley wheel to increase drivetrain efficiency. One derailleur ready for 2x or 1x, the steepest climbs and descents, all while shedding 12g from the previous generation Force. FEATURES: AXS is enabled for easy setup, personalization, and reliability Compatible with both 2x and 1x drivetrains Compatible with cassettes from 10-28T to 10-36T Larger X-SYNC pulleys for increased efficiency Chain management technology keeps the drivetrain quiet and secure Tehnology X-SYNC: SRAM X-SYNC 1x chainrings deliver the highest performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle-shaped teeth. The sharp, narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To deliver the best possible performance in muddy conditions, the X-SYNC chainrings feature 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 imitations. AXS: AXS is SRAM's new bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to view battery status, adjust component behavior, personalize controls, receive maintenance reminders, and update firmware. X-RANGE: Road bikes are faster and more capable than ever before, and riders are expanding what's possible with drop bar bikes. X-Range is geared for today's road riding. SRAM completely reimagined road gearing for a wider range, more useful and smoother gear progression, as well as smarter shift settings, enabled by AXS. With X-Range, you're always in the right gear.
