High body flexibility
and no pelvic rotation
Snake rides on Arione.
Snake does not rotate his pelvis when riding, but instead flexes his spine in order to reach the handlebar.
Most part of the rider’s weight will be carried by his sit bones. Snake saddles are long and flat to guarantee a precise match between the rider’s seat bones and the saddle surface, and to allow the maximum freedom of fore and aft movement on the saddle.
