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 BBRite and BB30/PF30 framesets. The Rotor 3D models allow for compatibility with standard BSA as well as press-fit BB90 frames.
The Wireless PowerMeter is offered in either a 110mm or 130mm BCD.
