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 ). 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 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.
