absoluteBLACK Oval 110BCD 5 Hole 50T 1x Chainring
This absoluteBLACK oval chainring is designed to work with cranks that have a 5 hole, 110BCD mounting format and is optimised for 1x gravel or road bike gear setups thanks to its 1.5mm offset and narrow-wide tooth profile. Made from stiff and long-lasting 7075 aluminium, this chainring grants stability and power transfer, while its oval shaping helps to reduce the rider’s oxygen consumption on demanding days in the saddle and lowers the risk of overuse injuries.
