The new crank arm design which is diamond-shaped has improved the rigidity of the component and thus distributes the applied weight better.
The previous system of closing the crank arm based on a glued cover using epoxy resins has been abandoned in favour of an internal procedure of structural union.
Our studies have shown in the common profile cranks straight or tapered toward the ends a major twist.
This twist is present in major form in the crank from the pedal connection up to about half.
The rhomboid shape invented by OMC-Italia has made stricter and cranks at the same time we got a better distribution of forces along the lever.
