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.

• Outer rings feature 6-point shifting ramps that work in conjunction with the tooth recesses to stabilize the chain while shifting, and allow for easy and quick gear changes
• For optimal shifting a 53/39T chainring combinations is recommended due to ramp design on large ring
• 134g
• Oval shape reduces stress on knees, helps to keep your legs fresh, and does not feel any different while riding
• Chainring design reduces the possibility of leg cramps, and allows you to maintain a better cadence while climbing
• For Gossamer and SL-K cranks use the original FSA hardware for installation
• For K-Force cranks you will need to purchase absoluteBLACK bolt covers for installation
