SRAM XG-1250 12-speed for Rival Bike Cassette

The SRAM XG-1250 12‑speed cassette, released for the 2026 model year, fits SRAM Rival road and gravel bikes. It offers a 10‑30T (or 10‑36T) steel sprocket range, FULL‑PIN construction, X‑Range gear gradation, and full compatibility with SRAM XDR freehubs and AXS electronic shifting.

The SRAM XG-1250 cassette is part of the Rival series and is designed for 12‑speed road and gravel drivetrains. It uses steel sprockets with a standard 10‑30T range, while a 10‑36T version is also available for riders who need a broader gear spread. The cassette incorporates FULL‑PIN technology, which presses lightweight steel cogs together with high‑strength pins, delivering a durable yet lightweight package. X‑Range technology provides uniform gear steps, often differing by only one tooth, to ensure smooth transitions between gears. Compatibility is limited to SRAM XDR freehub bodies and it works with SRAM's AXS electronic shifting system, confirming electronic_shift support. The cassette is specified for road bike use but performs equally well on gravel applications, reflecting its versatile design. With a 12‑speed layout, the XG-1250 maintains the drivetrain's overall efficiency while offering reliable shifting performance across the full gear range.
