Perfect for race machines and dream builds alike, the SRAM XX1 Eagle XG-1299 12-speed cassette for XD drivers offers top-of-the-line strength and weight savings—plus a range wide enough for any trail.


  • Ideal for 1x drivetrains, this 12-speed 10-52T cassette provides an expanded gear range of 520%, which is equal to that of 2 x 11-speed drivetrains
  • X-DOME technology creates an incredibly lightweight, precise and strong cassette; largest cog is made from aluminum, further saving weight
  • Open design aids in mud clearance, giving you cleaner shifting performance and longer component life
  • X-GLIDE 2 technology improves both inboard and outboard shifting, as well as chain retention
  • Titanium nitride surface treatment reduces friction and enhances wear
  • Compatible with XD drivers, which allow for the use of a 10-tooth small cog and offer an improved interface with the cassette
  • This cassette meets durability requirements for electric mountain bike (e-MTB) applications
