Chainrings

Original equipment on SRAM and Truvativ cranks, they also work well with other drivetrains. - Material: Aluminum

- Trushift chainrings feature shift ramps and pins - Drivetrain compatibility: 8, 9, 10, 11 - 104mm BCD

- The oversized chainrings are CNC machined 7075 Aluminium blanks—2mm thicker than the competition. - Unparalleled stiffness is delivered by an increased Bolt Circle Diameter (BCD) and a two-piece insert-molded carbon composite construction. - The XX Crank geometry provides a narrow 156mm Q factor, efficient chainline, and beveled crank arms to maximize clearance. - X-Glide is the pure science in action common denominator that gives XX its unmatched shifting performance. - 80mm BCD

Original equipment on SRAM and Truvativ cranks, these chainrings also work well with other drivetrains. - 104mm BCD - Material: Aluminum

- For 1x10 drivetrains - 104mm BCD - Material: Aluminum

- Designed for for Specialized 24/36T Crankset - Drivetrain Speeds: 2 x 10 - 104mm BCD
