Fit
20
NOTE: Correct fit is an essential element of bicycling safety, performance and comfort.
Making the adjustments to your bicycle which result in correct fit for your body and riding
conditions requires experience, skill and special tools. Always have a bicycle mechanic make the
adjustments on your bicycle; or, if you have the experience, skills and tools, have a bicycle
mechanic check your work before riding.
A. Standover Height
Diamond and Trapezoid Frame Bicycles
Standover height is the basic element of bike fit
(fig. 2). It is the distance from the ground to the top of the
bicycle’s frame at the point where your crotch is when
straddling the bike. To check for correct standover height,
straddle the bike while wearing the kind of shoes in which
you'll be riding, and bounce vigorously on the heels. If your
crotch touches the frame, the bike may be too big for you.
A bike which you ride only on paved surfaces and never
taken off-road should give you a minimum standover
height clearance of two inches (5cm). A bike that you'll
ride on unpaved surfaces should give you a minimum of
three inches (7.5cm) of standover height clearance. And a
bike that you'll use off-road should give you four inches
(10cm) or more of clearance.
Step-through Frame Bicycles
Standover height does not apply to bicycles with step-through frames. Instead, the
limiting dimension is determined by saddle height range. You must be able to adjust your saddle
position as described B without exceeding the limits set by the height of the top of the seat tube
and the “minimum Insertion” or Maximum Extension” mark on the seat post.
B. Saddle Position
Correct saddle adjustment is an important factor in getting the most performance and
comfort from your bicycle. If the position is not comfortable for you, visit an accredited bicycle
dealer for help.
The saddle can be adjusted in three directions:
1.
Up and down adjustment. To check for the
correct saddle height (fig. 3):
Sit on the saddle;
Place one heel on a pedal;
Rotate the crank until the pedal with your heel
on it is in the down position and the crank arm
is parallel to the seat tube.
If your leg is completely straight, your saddle height
needs to be adjusted. If your hips must rock for the heel to
reach the pedal, the saddle is too high. If your leg is bent
at the knee with your heel on the pedal, the saddle is too
low.
WARNING
: If your bicycle does not fit properly, you may lose control and fall.
