absoluteBLACK is committed to improving riders' pedalling action, and their Premium Oval 110BCD 5 Bolt Aero Chainring is part of this process. Both inner and outer chainrings feature smooth angled surfaces to help move the chain between rings when required. The chainrings do not have any cutouts, which retains stiffness aiding both power delivery and shifting.
