FSA MTB Chainrings - Which One is Right For You?

Full Speed Ahead offer mountain bikers a range of chainring options, ensuring that we meet the needs of the rider, whatever the requirement. Here one of our engineers discusses everything you need to know about our chainrings including gearing and drivetrain compatibility.


The brand new K-Force Light Evo pushes material technology to the limit to create a hugely strong yet light carbon crank. This twin-ring specific version means no weight is wasted on unused mounts that would only fill up with dirt. Even the Torx-headed chainring bolts are lightweight aluminum, while our ABS system – Asymmetric Bolt Spacing – puts extra strength behind the crank arm, right where it’s needed. The result is a very stiff, light crank: it’s just 495g. The chainrings are CNC machined from aircraft-grade 7075 aluminum, and ramped and pinned for optimum shift performance
