Sram Eagle XX SL XS-1299 T-Type Cassette - 12 Speed - Black / 10-52 / 12 Speed / Sram XD Drive

The SRAM XX SL XS-1299 T-TYPE 12S 10-52 Cassette offers the best gear shifting experience. Thanks to the X-SYNC design, the more you pedal, the better the shifting. It is the lightest Eagle cassette in history, as well as the most precise and long-lasting. The new generation features an X-Dome steel architecture fully mechanised and hardened for 1-9 gears, and an ultra-lightweight Spider cog made entirely of aluminium for 10-12 gears. Designed as a built-in or interdependent drivetrain component, the XX Eagle drivetrain cassette and derailleur come directly into contact, to guarantee perfect alignment for each bike. From the enormous range of 520% gear, the 52-tooth sprocket is a descendent of a progression of improved gear sprockets with 44 and 38 teeth on the lower edge (in comparison with the 10-52 tooth cassette of the Eagle drivetrain). With clearly marked configuration gears, installation is simple and infallible.
