absoluteBLACK Oval 110BCD 5 Hole 48T 1x Chainring
Perfect for road or gravel applications, the absoluteBLACK oval 48T 1x chainring is made from a hard-wearing and rigid CNC machined 7075 aluminium to promote excellent power transfer and mates with cranks that utilise a 5 hole, 110BCD mounting format. It features narrow-wide, 1x drivetrain inspired teeth to guarantee chain retention, while the oval shape helps to increase the rider’s pedalling smoothness and power, reducing fatigue and heightening efficiency on long or intense days in the saddle.
