With the SRAM XG-1275 GX Eagle 12-Speed Cassette, you'll be fast on the flats and in control on the climbs, no matter where you ride. Only Eagle technology can offer the 1x drivetrain that gives you infinite freedom. Full Pin technology, with lightweight, stamped steel cogs held together with high-strength stainless steel pins, makes this cassette both durable and light as a feather. The open design, similar to the X-Dome cassette, not only looks cool but also aids in mud clearance, giving you cleaner shifting performance and longer component life. The new X-Glide2 improves both inboard and outboard shifting, as well as chain retention, so you can take on whatever trail your heart desires.
