FSA KFX Boost Crankset

Why We Like The KFX Boost Crankset

Carbon cranks aren’t for everyone, so the aluminum enthusiasts among our ranks opt for the KFX Boost Crankset for its high-performance design that also boasts a durable aluminum construction. These cranks are CNC-machined with a hollow construction for a ride feel that is lightweight, responsive, and ultra-stiff for pedaling efficiency. They’re perfect for general trail riding, and the aluminum construction also offers excellent vibration damping characteristics for rough enduro riding.
