Rotor 3D+ Cranks (BB30 with Aluminium Axle)
Lighter and more stylish than ever before, the Rotor 3D+ Cranks (BB30 with Aluminium Axle) is new and comes in at 40 grams less than it's predecessor. Saving weight and getting stiffer are both results of the new 7055 alloy construction. Incorporating a 30 millimetre axle and BB30 technology.
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 does not impact on strength. Leading the way in crankset design the high precision pre-load bearings are easily adjustable using the compression lockring, that uses a fine thread.
