Description of Rotor REX 1.1 MTB Crankset 1-speed - Cannondale F-Si Ai - black

You´ve been brand-loyal since the F700 debuted in the 1996 Olympics — or maybe you're a history buff with an appreciation for fine craftsmanship. Whichever it is, you can have it both ways with our REX 1.1 cranks for your Cannondale F-Si Ai frame. In addition to biomechanical performance, there was one more important factor when designing REX 1x cranks: compatibility. ROTOR wanted everyone to be able to experience REX cranks so they designed the REX 1.1 Cannondale F-Si Ai specifically for Cannondale's asymmetric integration frames. Crank arms CNC-machined from aeronautic-grade 7055 aluminum are combined with proprietary technologies to yield cranks with an exceptional stiffness-to-weight ratio that can handle a thrashing off-road.
