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.


As the range of rear cassettes gets ever-larger, the need for a big range at the front diminishes and double chainring setups for MTB are increasingly popular. Comet brings a stiff, modular 1x crankset with a 24mm alloy spindle in at a high-value price. Solid forged 6061 aluminium arms put the power down and they’re channeled at the back to trim some weight. A new No Pinch Bolt design on the left-hand crankarm makes fitting easier and looks cleaner. Modular configuration allows the compatibility with boost 148 frames.

  • Thick-thin tooth design for maximum chain engagement
