SRAM Truvativ XX Chainring

Description

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
