The GX Eagle T-Type AXS 12-Speed derailleur is a lesser version of nothing. It delivers everything an Eagle Transmission derailleur possibly can, and then some. It features a revised battery position and a reconfigured gearbox to better protect itself from impacts. To maintain crisp shifting and striking appearance throughout its entire lifespan, hard-chargers can replace both its protective skid plates and two-piece outer link, if needed, making this the most repairable derailleur SRAM has ever made. It also features the first ever tool-free cage and clutch assembly - so it's both removable and upgradable too. Just like all Eagle T-Type derailleurs, it's been engineered with a first-of-its-kind Hangerless Interface, mounting around the wheel axle itself and making direct contact with the cassette with no hanger required (Requires frame with UDH interface). The new transmission derailleurs feature the same intuitive pairing and set-up procedure as our Eagle AXS derailleurs. Revolutionary Hangerless interface and Full Mount attachment method creates a far stronger connection because it grips both sides of the frame (Requires frame with UDH interface) Steel inner cage adds even more robustness Installs and pairs via the reliable and familiar standard AXS set-up and pairing procedure Radically clear setup process, no adjustment required Battery Not Included Item Specifications Color Black Drivetrain Speeds 12 Largest Cog 52 Rear Der/Shifter Compatibility SRAM eTap AXS SRAM GX Eagle T-Type AXS Rear Derailleur Rear Derailleur UPC: 710845892929

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!

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!
