SRAM RED XG-1290 Cassette - 12-Speed, 10-36t, For XDR Driver Body, Silver, E1

Road racers and fast gravel riders chasing every gram run the SRAM RED XG-1290 (CS-XG-1290-E1), a 12-speed cassette. One-piece X-Dome machined steel construction drops weight to 232 grams while keeping the block stiff and durable.

The 10-36t range with a 10-11-12-13-15-17-19-21-24-28-32-36 progression holds tight, single-tooth steps across the fast cogs where racers hunt cadence, then opens up for climbs. It mounts on an XDR driver body and meshes with SRAM RED AXS 12-speed Flattop chains.

As the RED-tier cassette atop the SRAM road hierarchy, its 232-gram weight and one-piece steel build serve riders who count grams at race pace.
