The SRAM Force AXS E1 12-Speed 36T Rear Derailleur is a lightweight, high-efficiency component built for precision, range, and smooth wireless shifting. With a redesigned carbon cage and larger X-SYNC pulleys, it delivers improved drivetrain efficiency while handling 10-36T cassettes with ease. Whether running a 2x or 1x setup, it offers quiet, secure chain management and compatibility across a wide range of gearing.Key Features and Benefits:Wireless AXS shifting protocol: Offers fully electronic shifting with precise control. This ensures consistent, lag-free performance. The result is reliable gear changes even under load.Supports both 2x and 1x drivetrains: Adapts easily to different setups without requiring a separate derailleur. This gives riders more flexibility in bike configuration. The outcome is streamlined inventory and easier system upgrades.Compatible with 10-28T to 10-36T cassettes: Covers a broad range of gearing options with one derailleur. This helps fine-tune gear ratios for varied terrain. Riders benefit from better cadence control on climbs and descents.Larger X-SYNC pulley wheels: Reduces friction in the chain path for smoother drivetrain function. This improves power transfer and extends component life. The outcome is better pedalling efficiency and reduced wear.Integrated chain management technology: Keeps tension on the chain to prevent drops and slap. This protects the frame and maintains a quieter ride. The result is a more stable and low-maintenance drivetrain.Carbon cage construction: Lowers overall weight while maintaining strength and stiffness. This contributes to a 12g weight saving over the previous version. Riders enjoy a lighter bike without compromising durability.This derailleur is designed for riders who want smooth shifting across a wide gear range without added bulk. Its wireless operation, cage refinement, and compatibility with a full 10-36T cassette make it ideal for tackling steep climbs, fast descents, and everything in between. It supports both 1x and 2x systems, giving you the freedom to build your drivetrain your way while gaining efficiency and reducing weight.Engineered for precise performance and a wider gear range, this derailleur brings speed and reliability to every ride. Upgrade your drivetrain with a single, versatile component that keeps shifting smooth and consistent.Specification:Speed (RD) 12Max tooth 36Colour (RD) Unicorn Black w/Laser FoilPulley bearings material SteelCage material (RD) CarbonDrivetrain Configuration 2xCommunication Protocol AXSShift Technology WirelessChain Technology Road Flattop D1, Road Flattop E1Battery Not Included
