SRAM Force XG-1270 E1 Cassette
Product Details
The new SRAM Force XG-1270 cassette is engineered for modern road cyclists who demand precision, range, and reliability in a lightweight package. Built to seamlessly integrate with SRAM’s 12-speed AXS drivetrains, it combines advanced construction with refined gearing progression to deliver optimal performance across varied terrain, from fast road rides to all-day mixed-surface adventures.
At the heart of the cassette is SRAM’s X-Range technology, which reimagines road gearing with smoother progression and a wider range. A 10-tooth start across all configurations, including 10-28T, 10-30T, 10-33T, and 10-36T, ensures tighter gear steps where it matters most. This keeps you in the ideal cadence whether climbing, sprinting, or cruising. The 10-28T, 10-30T, and 10-33T versions feature at least five one-tooth jumps, delivering a smoother, more natural feel under power.
Construction is optimized for strength and lightness using SRAM’s proven FULL PIN technology. Eleven stamped steel cogs are held together by 123 high-strength stainless steel pins, creating a lightweight yet durable structure capable of handling high torque and efficiently clearing debris, perfect for performance in all conditions. Nickel chrome plating adds durability and ensures quiet, consistent shifts.
Designed to mount on an XDR driver body, the XG-1270 offers broad compatibility without requiring new rear axle standards or special tools. Whether optimizing for race-day performance or building an all-around endurance setup, this cassette delivers flexibility and responsiveness to ride your way.
The SRAM Force XG-1270 cassette is more than just a gearing choice; it’s the foundation for a drivetrain that works smarter, shifts smoother, and climbs faster.
