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.
