Go ahead, shift through the climbs
The XX SL Eagle T-Type Cassette is a major reason why Eagle Transmission offers pristine inboard and outboard shifting performance under load. Thanks to its full X-SYNC design, the harder you pedal, the better it shifts. But not only is it precise, it's also insanely light and built with durability in mind.
Its new-gen features a fully machined, hardened steel X-Dome architecture for gears 1-9 and an ultra-lightweight, all-aluminum Spider Cog for gears 10-12. Engineered as integrated and interdependent transmission components, the XX Eagle Transmission Cassette and derailleur contact directly to provide perfect alignment on every bike. From its massive 520% gear range, the 52 tooth cog steps down with improved gear progression with 44 and 38 tooth cogs in the low end (compared to the Eagle drivetrain 10-52-tooth cassette).

SRAM Eagle Transmission is unlike any other drivetrain
SRAM Eagle T-Type drops a seismic shift on what it means to shift a mountain bike. Built around the universal constant of the wheel axle itself, Eagle Transmission is a radically robust, fully integrated and interdependent wireless transmission that literally changes how you ride.
"Transmission is truly game-changing, and that's not a phrase I use lightly"
"if I could choose any drivetrain on the market, cable actuated or electronic, I'd go with Eagle Transmission – it's that good."

"it’s called a “transmission” because everything is interdependent in ways that current “drivetrains” are not...With a transmission, there’s no mixing or matching — it’s a complete group that’s optimized as a system."
