your bike's seat height is a simple way to improve the comfort and
safety of your ride. It's easy to determine the right height-simply
place your feet in the toe cages or clip into the pedals and rotate the
pedals until one leg reaches the bottom of the pedal stroke. Make sure
there is a 25-35 degree bend in the lower knee.
seat also adjusts forward and backward, so that your knees will be
properly aligned relative to your feet. Sit on the saddle in riding
position, with your hands on the handlebars and the balls of your feet
over the center of the pedals. Then position the pedals so they're
level with each other. Use your forward leg for the alignment check.
Picture an imaginary line (or have someone hold a plumb line) from the
front of your kneecap straight down. Your seat is in the right position
when your knee cap is directly above the center of the pedal.
Adjust the handlebars to a position that is comfortable and limits unnecessary strain on your neck and back.
If toe cages and straps are used,
be sure to align the ball of your foot over the center of the pedal.
This is the firmest, widest striking surface on your foot and therefore
the most efficient and comfortable foot position.
If clipless pedals are used,
check the cleat tension on the pedals and make sure that your cleats
are aligned properly on your shoes. Some cyclists prefer to mount the
cleats on their cycle shoes so that the ball of the foot is slightly
forward or behind the center of the pedal.
