Rear Sprocket Aluminum 49t 520 Red Hon

Features:

• 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
