With 184mm Zencranks I had an enhanced ability on the plains and maintained 150watt 50-11 in the 35km in plains effortlessly, while uphill I did not detect any improvement.

...and the research continues, thanks to the cooperative efforts and availability of many cyclists who have been testing Zencranks PAS: following the almost unnoticeable increase in performance experienced in February 2011 by Max Grazia, the small interchangeable arms have been modified optimizing performance in both group at high cadence and when pushing big gears.

A new configuration has been tested specific for endurance with a result of extreme fluidity at high cadence: ideal in races and training with the pedal set at 90° on the small interchangeable arm, while a 45* has been proven to be ideal for chrono (this accentuates the length of the lever when the foot is in the lower front circular trajectory of the pedal stroke. In Max Grazia's specific case with cranks of 184mm it gets to 188mm of effective lever and in the recovery up coming rear stroke we have a 174mm lever length. This new geometry lower torque that enhance the acceleration when seated with big chain rings, optimal in chrono (after turns and in uphills) as it helps to maintain a steady cadence.
