The secret of ROTOR's cranks design Endurance.
All Rotor cranks are certified to both EN14766 (MTB) and EN14781 (Road) standard.
Let us explain the demanding test which ensures the customer a bomb proof product.

Apply repeated vertical dynamic force of 1800nm alternatively to the pedal spindles of left and right hand cranks at a distance of 65mm from the face of the cranks, repeating for 50,000 cycles with the cranks arms at 45 degs to the horizotal.
This is whilst the chainrings are held confined by a jig to prevent the assembly from rotating.
This test is proving all aspects of crank arms, spider and connections. All this performed at a frequency of 25hz.

3D models which are well known in the market for their stiffness to weight ratio. The best choice for the demanding cyclist demanding extreme rigidity but concerned about weight.
