A tireless powerhouse for those who ride hard and never hold back. No compromise on durability, reliability and wireless functionality. Combining the latest technologies from the Eagle ranges with the best possible price, the GX Transmission group is more than ready to take on any challenge.

SRAM GX Eagle Transmission cassette

One of the main reasons that the GX Eagle Transmission drivetrain system provides the best shifting characteristics even under load, is the perfectly matched T-Type cassette. The cassette and the rear derailleur of the GX Eagle series are designed as integrated and interdependent transmission components that mesh directly with each other to ensure perfect alignment on any bike.

The stronger the rider pedals, the more the Full X-SYNC™ tooth design of the XS-1275 cassette plays out its potential and improves the shifting performance accordingly. With the help of the large 52-tooth sprocket, the 12-speed cassette not only comes to a huge gear range of 520 %, but is also much more durable and precise.

While the so-called PinDome design is used for the 8 large sprockets (gear 1 to 8), the one-piece Mini-Cluster construction improves durability in the area of the 4 smaller sprockets (gear 9 to 12). The nickel coating not only ensures first-class corrosion and wear resistance, but also quieter shifting behavior.

Features of the GX Eagle T-Type cassette

• Full X-SYNC™ tooth design for the best shifting performance under load and in both directions
• 520 % gear ratio range with optimized gear jumps in the lower range thanks to the sprockets with 38 and 44 teeth
• small sprocket with 10 teeth to extend the gear ratio range
• tuned to 55 mm chainline for lower chain angle and correspondingly less wear and higher precision
• nickel coating for more durability and quieter shifting behavior
• clearly marked setup cog for a simple and tool-proof assembly
• compatible with XD freewheels

Note: Only compatible with SRAM Eagle Transmission drivetrains and T-Type components only.

X-SYNC™ | The sophisticated tooth design with high, square edges ensures maximum performance and durability. Not only the narrow, sharp tooth profile grips the chain earlier than teeth with the traditional triangular shape, also the rounded chamfer edges support the chain's guidance. In addition, to withstand adverse conditions, X-SYNC™ chainrings are provided with mud-repellent recesses, which protect the links and rollers of the chain from dirt.
