Rotor VEGAST 24mm Crank Arms Forming part of an innovative and versatile modular system, the Rotor VEGAST 24mm Crank Arms are combined with Rotor’s matching spiders, axles and chainrings to create a personalised crankset suited perfectly to a rider’s requirements and preferences. These crank arms utilise a super high grade of 6082 aluminium that is naturally lightweight, rigid and durable. They are manufactured using a detailed CNC machining process that creates a svelte aesthetic and the Trinity drilling process that fashions three hollow internal cavities, running the length of the crank arms, to reduce weight markedly without sacrificing integrity. A direct mount format connects these crank arms to the spider and axle to form an efficient platform that translates power directly from the rider into forward drive. This system also makes maintenance incredibly easy as all of the crankset components are connected with just one bolt. Linking to the 24mm version of the Rotor ALDHU/VEGAST axle, a large selection of bottom bracket interfaces are catered for to increase versatility across a wide scope of road bikes.
