SADDLE ADJUSTMENT
Saddle Height
:
When your saddle height is adjusted properly, you should
have a small bend in your knee when your foot is at the bot-
tom of the pedal stroke and you are sitting comfortably. If
you have the saddle height too low, you will lose pedaling
effi ciency and will have to work much harder-we defi nitely
don’t want that. If you have the saddle height too high, you
will be stretching just to pedal and your pelvis will have to
rock side to side with each pedal stroke. Adjust the saddle
height by opening and then closing the quick release lever.
