Fit

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 your dealer make the adjustments on your bicycle; or, if
you have the experience, skill and tools, have your dealer check your work before riding.
WARNING: If your bicycle does not fit properly, you may lose control and fall. If your new bike doesn't
fit, ask your dealer to exchange it before you ride it.
A. Standover height
1. Diamond frame bicycles
Standover height is the basic element of bike fit (see fig. 2). It is the distance
from the ground to the top of the bicycle's frame at that 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
your heels. If your crotch touches the frame, the bike is too big for you. Don't even
ride the bike around the block. A bike which you ride only on paved surfaces and
never take off-road should give you a minimum standover height clearance of two
inches (5 cm). A bike that you'll ride on unpaved surfaces should give you a
minimum of three inches (7.5 cm) of standover height clearance. And a bike that
you'll use off road should give you four inches (10 cm) or more of clearance.
2. 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 in 3.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 saddle position is not
comfortable for you, see your dealer.
The saddle can be adjusted in three directions:
1. Up and down adjustment. To check for 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 not 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.
Ask your dealer to set the saddle for your optimal riding position and to show you how to make this adjustment. If
you choose to make your own saddle height adjustment:
• loosen the seat post clamp
• raise or lower the seat post in the seat tube
• make sure the saddle is straight fore and aft
• re-tighten the seat post clamp to the recommended torque (Appendix D or the manufacturer's
instructions).
Once the saddle is at the correct height, make sure that the seat post does not project from the frame beyond
