absoluteBLACK Oval Rainbow SRAM Direct Mount 3mm Offset 1x Chainring

This absoluteBLACK Oval chainring is designed for use with SRAM direct mount cranks, has a 1x specific 3mm offset to work optimally with bikes that have a Boost configuration, and is finished in a durable but beautiful rainbow titanium coating. Made from 7075 aluminium, power transfer is guaranteed, while the narrow-wide profile of the teeth stop awkward chain drops and improve mud shedding in poor weather conditions.

Designed for 9, 10, 11 and 12-speed drivetrains, a full spectrum of gear setups are catered for, and the innovative oval format helps the rider realise increased pedalling efficiency and more comfort on long or intense days in the saddle.
