ROTOR Aldhu cranks offer a unique balance of weight and stiffness to our users. With just 348g for the 170mm cranks thanks to their machined 7075 aluminium construction. In addition, these cranks incorporate Trinity Drilling System® technology. This lightens the cranks by using three longitudinal hollow holes along the inside of the crank arm, removing unnecessary material.

In addition, Aldhu cranks offer a wide variety of configurations to suit every rider's preferences and needs. Thanks to our innovative modular structure, as well as the different axle and chainring options, each component is individually available to suit today's range of users and cycling standards.

TDS® — Engineered differently

The Trinity Drilling System (TDS®) is ROTOR’s exclusive machining technology that transforms our aluminium crank arms through a precision triple-drilling process. The result is a crank arm that is lighter and stronger, but above all delivers unmatched stiffness. Superior to any aluminium or carbon crankset on the market and only comparable to the very best titanium cranks.

Ultra-light aluminium, steel-like strength

Precision-machined from aerospace-grade 7075-T6 aluminum alloy. This material delivers an optimal balance of stiffness, hardness, and high strength comparable to steel, combined with the lightweight performance of aluminum and total resistance to corrosion.

Spindle options: compatibility or performance

Aldhu cranks stand out by giving you a choice of spindles. Choose the 24mm steel spindle for seamless compatibility with Shimano® bottom brackets. Or, step up to our 30mm spindle: made of 7075-T6 aluminum, its thicker design makes it both lighter and stiffer. Choose the perfect option for your setup.
