Rotor 3D+

Rotor 3D+

The Rotor 3D+ road crank is extremely stiff to meet the demands of sprinters but also lightweight to satisfy the needs of climbers. 8 strain gauges guarantee the familiar SRM high accuracy and reliability.

ROTOR utilizes a special manufacturing process, named the "Trinity Drilling System". It is a unique triple hollow crank arm that enables the removal of the excess aluminum in the core while still maintaining the structural strength of the crank.
