Rotor VEGAST Track crank arms, spider & axle

Much like Rotor's ALDHU crank arms, the VEGAST utilizes a special manufacturing process named the “Trinity Drilling System", where an extruded aluminum bar is intricately CNC machined with three internal holes through the length of the crank, resulting in the dual benefit of an exceptionally light, strong semi-hollow crank arm with superior stiffness. The VEGAST Track also features a disc-style spider and 30mm proprietary axle system, offering both aerodynamics and extremely stiff power transmission. Can be paired with any 144mm bcd track chainring of your choice (you do not need to use a Rotor chainring). Includes arms, axle, disc spider & proprietary M10 chainring bolts.   Professional assembly and installation using a torque wrench and following all published torque specifications is strongly recommended.
