SRAM X0 Eagle T-Type 12 Speed Flattop Chain

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.

The SRAM XO T-TYPE Eagle 12-speed chain is a high-performance lightweight chain that features a unique design for significantly improved wear resistance on Eagle T-TYPE cassettes and rings.

How do I know what size chain to use with Eagle Transmissions? Chain length for Eagle Transmissions is determined by the chainstay length of the bike at full extension (not compressed), and the chainring size. Chain length can be found in the AXS app set-up guide and in the manual.
