Zencranks PAS (Power Augmentation Systems), crank lengths of 170-175 mm
Foot trajectory (at metatarsus level) while pedaling: 175mm traditional crank arms with Keo pedals (blue) 190mm Zencranks PAS (Power Augmentation System) with Keo pedals
Thickness including pedal axel (above its own center), pedal, cleat and sole for a total of 320mm circumference length with 175mm traditional crank arms with Keo pedals = 1028mm circumference length with 190mm Zencranks PAS with Keo pedals = 1,154mm
Note: The trajectory of the pedal on the way up when using Zencranks is closer to the vertical axel and the trajectory of the 175mm standard cranks because the foot in such area is tilted approximately 45° forward.
