The SRAM X-Glide 11-speed Chainring is 5mm thick for added stiffness and decisive shifting control. With the same upshift rivets that make SRAM'S XX mountain groupset so fast, the X-glides are made from CNC-machined 7075-T6 aluminum for precise shape and ramp. Ideal for use with SRAM X-glide chains, chainrings, and front derailleurs, this 11-speed Chainring ensures you can always find the next gear when you need it.
