Description

The SRAM Force XG-1270 E1 cassette is the ideal choice for 12-speed drivetrains in SRAM Force AXS electronic groupsets.
Designed with X-Range™ technology, it offers a wide range of gears and smoother, more progressive shifting. The 10-tooth first cog ensures greater versatility and optimized overall range, perfect for road, gravel, or endurance bikes.

Made with steel sprockets and an aluminum final sprocket, it is constructed with Full Pin technology which ensures lightness, rigidity and durability over time.
The nickel-chrome finish reduces noise and improves corrosion resistance.
Compatible with XDR™ body and D1 and E1 series Flattop chains.

Assembly and maintenance

• Install the cassette on a clean and properly tightened XDR body.

• Use a torque wrench and respect the torque indicated by SRAM.

• Keep your chain clean and lubricated to extend the life of your cassette.

• Periodically check for wear with a special gauge and replace components if they vibrate or make abnormal noise.
