absoluteBLACK Premium Oval 110 BCD Chainrings utilize absoluteBLACK's top-tier design features to greatly improve traction and speed. They are designed for 4-bolt or 5-bolt FSA cranks such as Gossamer, SL-K, and K-Force with asymmetric bolt spacing. 4- and 5-bolt cranks are identical with the exception of the one hidden bolt behind the crank arm in 5-bolt design, which is not needed. Optimized with smooth shifting in mind, premium chainrings have a unique shift ramp and recess design. Chainrings are crafted from CNC machined 7075 aluminum and feature an anodized finish for exceptional durability.
