The SRAM 110 mm Red 22 Chainrings offer factory replacement options for Red 22 cranksets. These 5 mm thick CNC-machined alloy X-GlideR chainrings provide optimized stiffness and shifting performance with outer-ring specific ramps and pins to aid chain transition. These 11-speed chainrings work best with SRAM chains and SRAM Yaw front derailleurs.
