absoluteBLACK Oval 110BCD 4 Hole 1x Chainring

This absoluteBLACK 1x Chainring is compatible with cranks that have a 110BCD, 4 hole mounting format and possesses an innovative oval shape. This shape maximises the rider’s power on the downstroke of the pedal cycle, but lessens the resistance through the dead spot to significantly reduce fatigue and oxygen consumption on demanding rides. The oval shape also minimises the chances of annoying overuse injuries, particularly in the knees. 

Made from a CNC machined 7075 aluminium, this chainring is stiff and durable, and the narrow-wide profile of the teeth cancels the chances of chain drops on bumpy riding surfaces and quickens mud clearance in heavy conditions.
