Aluminum Rear Sprocket 49T – Black

Description

• 7075-T651 Aerospace aluminum. The strongest commercial grade aluminum chosen for maximum tooth strength to offer extended sprocket and chain life.
• 100% surface anodized finish. Critical to prevent oxidization caused by untreated aluminum. Helps prevent the sprocket becoming loose on the wheel.
• CNC machined to provide perfect fitting to the bike hub.
• CAD design allows the maximum removal of weight, while keeping core strength.
• Grooved to prevent dirt build up under chain and prolong chain life.
• Factory tooth design, developed with factory teams. The wider and stronger tooth provides up to 20% longer sprocket life.
• Larger tooth radius reduces chain friction and extends chain life
