absoluteBLACK Silver Series Oval 110 BCD Chainrings feature many of the same benefits as absoluteBLACK's Premium line, but with less material machined out on the outer side, allowing for easier maintenance and cleaning. They are designed for pre-2014 5-bolt cranks such as Shimano Dura-Ace FC7900, Ultegra FC6750, Shimano 105 5750 and more. They are designed for Shimano 4-bolt cranks such as Dura-Ace 9000, Ultegra 6800, 105 5800 and others. Optimized with smooth shifting in mind, these chainrings have a 6-point ramp and recess design. Chainrings are crafted from CNC machined 7075 aluminum, and feature an anodized finish for exceptional durability.
