• Flattop Chain Compatible: Designed for use with SRAM Road Flattop D1 and E1 chains

Product Overview
The SRAM Force XG-1270 D1 cassette is designed to provide the smooth gear progression and wide gearing range demanded by modern road and all-road drivetrains. SRAM's X-Range gearing philosophy uses a 10-tooth smallest sprocket to increase overall range while maintaining useful steps between gears, helping riders maintain an efficient cadence across changing terrain.

MINI CLUSTER construction combines four smaller cogs machined from a single block of billet steel with eight individually pinned cogs, creating a cassette that balances low weight with the durability required for regular riding and training. The gearing is optimised for electronic shifting, helping SRAM AXS drivetrains deliver consistent and precise shifts throughout the cassette.

With 10-28T, 10-30T, 10-33T and 10-36T options available, the XG-1270 can be configured for everything from fast road riding and racing to rolling terrain and demanding climbs. Compatibility with both 1x and 2x drivetrains makes it a versatile cassette for a wide range of SRAM AXS road setups.

Compatibility & Notes
Requires an XDR-compatible freehub body and a compatible SRAM 12-speed Road Flattop drivetrain. Rear derailleur cassette capacity varies between SRAM AXS derailleur models, so confirm that your derailleur supports the selected cassette size before installation. SRAM notes that XG-1270 cassettes produced before 2021 used a black finish, while the design was subsequently updated to a nickel-chrome/silver finish.

Care & Notes
Keep the cassette and chain clean and correctly lubricated to maintain smooth shifting and minimise drivetrain wear. Check the cassette periodically for worn teeth and ensure installation is carried out to SRAM's specified procedures and torque requirements. For best shifting performance, use with compatible SRAM Road Flattop chains and AXS drivetrain components.
