SRAM XS-1299 XX SL Eagle Transmission 12-Speed Cassette

The SRAM XS-1299 XX SL Eagle Transmission 12-Speed Cassette features an all-new full X-SYNC design which means the harder you pedal, the better it shifts! In addition, it features a fully machined, hardened steel X-Dome architecture for gears 1-9 and an ultra-lightweight, all-aluminum Spider Cog for gears 10-12. This makes it ultra-lightweight and strong. In fact, it’s SRAM’s lightest ever Eagle cassette!

The SRAM XS-1299 Eagle XX SL cassette and derailleur also contact directly, which ensures perfect alignment on every ride. You also get a massive 520% gear range and the 52 tooth cog steps down with improved gear progression with 44 and 38 tooth cogs in the low end.
