Description
Rotor 3D+ MAS (micro adjust spider) Road Cranks
One of the most versatile cranks in the Rotor range, the Rotor 3D+ MAS (micro adjust spider) Road Cranks, using it's MAS technology, offers another option in bolt hole positioning. This allows for further positioning possibilities in between existing OCP settings on Rotor Q-Rings. This new system allows for minute adjustments in chainring positioning to truly refine your riding style. With a conventional crankset offering approximately 5 degrees of adjustment, the new MAS spider designed crank delivers half position precision to set the chainrings up to a mere 2.5 degrees.
Saving weight and impressive levels of stiffness are both results of the, state of the art, 7075 T6 CNC alloy construction. Incorporating a 30 millimetre axle and UBB30 technology. This makes the chainset compatible with a wide range of bikes, both 30 millimetre axle ready or not.
Featuring Rotor's pioneering Trinity Drilling Process, a manufacturing process that, using CNC machining, produces a triple hollow crank arm from an aluminium block. The weight saving is achieved with excess aluminium being extruded, yet this process does not have an impact on strength.
