ALUGEAR Aero 107 BCD Chainring

The ALUGEAR Aero 107 BCD Chainring is made for 107 BCD SRAM cranksets and the 107 BCD Quarq power meter. It uses a tooth profile that makes it compatible with a wide range of 11- and 12-speed chains. This chainring is CNC machined from 7075 T6 aluminum and hard coat anodized to improve durability and provide protection from mechanical impacts. It also features an aero design that helps reduce drag by reducing gaps found on traditional chainrings.
