Incredible stiffness to weight ratio

The Trinity Drilling Process creates an ultra-light CNC machined crank set

The SRM-Rotor PowerMeter is offered in two different crank options, the 3D and 3D+. Both cranks use the Trinity Drilling Process to create three holes drilled end to end, length-wise, through a solid piece of aluminum. This allows for an extremely low weight as well as an optimized weight to rigidity ratio. The Rotor 3D+ crank set is also the choice of the Garmin Sharp Professional Cycling Team. The SRM-Rotor PowerMeter allows for more compatibility between frames and gives the same precision and durability found throughout the SRM Product line. The Rotor 3D+ model SRM PowerMeter allows for direct integration into BBRight and BB30/PF30 frame sets. The Rotor 3D models allow for compatibility with standard BSA as well as press-fit BB90 frames.

3D Crank: Available in both 130mm BCD (53/39) and 110mm BCD (50/34).
