Ein fernerer Vorzug besteht darin, daß beim Anbringen der Feder das Pedal nicht abgenommen zu werden braucht.This construction has the advantage over other resilient pedals that when pedaling of the pedal, there is no sliding and no friction on the spring, thereby avoiding discrepancies will. Another advantage is that when attaching the spring Pedal does not need to be removed.
