- 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.
- 120mm BCD
- C-Pin for Cannondale
- Short Pin for BB30
