absoluteBLACK SRAM Oval Direct Mount Boost Chainring for Shimano HG+ Black, 34t, Hyperglide Plus (M9100, M8100, M7100)

Designed to partner with Shimano's 12-speed Hyperglide+ chain, the SRAM Oval Direct Mount Boost Chainring converts any SRAM crank into a Boost setup for improved efficiency and control. The chainring's oval shape is designed to maximize power in the portion of the pedal stroke where power is produced, and minimize resistance where it isn't, delivering improved efficiency through difficult climbs and technical terrain. To strengthen longevity and reliability, Absolute Black constructed the chainring with anodized aluminum and edge shaping that sheds mud and grit with ease.
