This SRAM GX Eagle Transmission T-Type AXS rear derailleur is the 12-speed, 52T model with a steel cage and black finish. It uses SRAM's hangerless Full Mount system on a compatible UDH frame interface. The AXS battery is not included. This is a replacement derailleur, not a complete drivetrain conversion kit. Will it work on my bike? You need a Transmission-compatible frame with the UDH interface and the appropriate T-Type chain, cassette and compatible chainring setup. The derailleur mounts around the rear axle interface after the UDH hanger is removed. It does not simply screw into a conventional derailleur hanger, and it is not a direct replacement for a non-T-Type GX Eagle AXS derailleur on an older drivetrain. For a new build or conversion, account for the compatible AXS controller, battery and charging equipment as well as the rest of the drivetrain. Existing AXS controllers can work with Transmission when correctly paired, so check what you already own before buying duplicate parts. Verify frame compatibility using SRAM's bike compatibility information and the bike manufacturer's guidance. Why choose GX Transmission? GX brings the Transmission mounting and shifting system into a durable, serviceable package. Its battery position helps shield the battery from impacts, while replaceable skid plates and outer-link parts give you options if a rock leaves its signature. The cage and clutch assembly can be removed without tools for the specified service procedures. The steel inner cage favors robustness over the lightest possible build. The derailleur is one part of the Transmission system. Correct chain length, setup-key position and installation sequence still matter; hangerless does not mean setup-free. Follow SRAM's procedure for the bike rather than treating it like a conventional limit-screw and B-gap adjustment.

SRAM Eagle Transmission Rear Derailleur Can you believe that SRAM released its first 12-speed Eagle drivetrain over six years ago? And it's even been four years since SRAM Eagle AXS first came out! Yes, those pandemic years are blurry and time has been oddly fast since 2020. But those two statements above are true, and now SRAM is back to update its Eagle ecosystem once again with the new SRAM Eagle Transmission Drivetrain. A lot has changed but also not so much at the same time. It's still 12-speed, it's still the same wireless AXS shifting that we love, so why the update? Well, a few years ago SRAM started to make the SRAM UDH, a Universal Derailleur Hanger that helped solve the crisis and headache of finding the right derailleur hanger for your bike. It helped consumers, bike shops, and even bike brands as they just needed the design from SRAM and could work that into their bikes. Over the past few years, lots of brands have implemented this on their mountain bikes, including some of the biggest brands in the world. Now, SRAM has taken advantage of all of these bike brands using their UDH design, and the new Eagle Transmission rear derailleur mounts directly to the frame. SRAM Transmission is offered in full five-piece kits at first, similar to how things were back when Eagle mechanical and Eagle AXS were first released. The different tiers have changed a bit as well. We now have XXSL, XX, and XO, going from the lightest and XC race focused with XXSL, to the all-mountain drivetrain with XX, and last but certainly not lower in performance, the XO which comes with an alloy crank. Not only does the SRAM Eagle T-TYPE Rear Derailleur get the job done, it features everything you have come to expect from SRAM's AXS connect components .

SRAM Eagle Transmission Rear Derailleur Can you believe that SRAM released its first 12-speed Eagle drivetrain over six years ago? And it's even been four years since SRAM Eagle AXS first came out! Yes, those pandemic years are blurry and time has been oddly fast since 2020. But those two statements above are true, and now SRAM is back to update its Eagle ecosystem once again with the new SRAM Eagle Transmission Drivetrain. A lot has changed but also not so much at the same time. It's still 12-speed, it's still the same wireless AXS shifting that we love, so why the update? Well, a few years ago SRAM started to make the SRAM UDH, a Universal Derailleur Hanger that helped solve the crisis and headache of finding the right derailleur hanger for your bike. It helped consumers, bike shops, and even bike brands as they just needed the design from SRAM and could work that into their bikes. Over the past few years, lots of brands have implemented this on their mountain bikes, including some of the biggest brands in the world. Now, SRAM has taken advantage of all of these bike brands using their UDH design, and the new Eagle Transmission rear derailleur mounts directly to the frame. SRAM Transmission is offered in full five-piece kits at first, similar to how things were back when Eagle mechanical and Eagle AXS were first released. The different tiers have changed a bit as well. We now have XXSL, XX, and XO, going from the lightest and XC race focused with XXSL, to the all-mountain drivetrain with XX, and last but certainly not lower in performance, the XO which comes with an alloy crank. Not only does the SRAM Eagle T-TYPE Rear Derailleur get the job done, it features everything you have come to expect from SRAM's AXS connect components . It's able to shift on command, whether that's under climbing load, or sprinting to the stage finish. The derailleur is smart enough to protect itself thanks to its incredibly resilient Overload Clutch. Engineered with a variety of rider preferences in mind, it is compatible with the expanded range 10-52t T-TYPE cassette Read our blog with all the new SRAM Components along with our first impressions!
