The only adjustment you should need to make is the extension of your seat post, and
possibly the position of the saddle on the seat post. Most people find that the seat height is
comfortable when the top of the seat is level with the outer edge of your hip bone when you
are standing next to the bicycle. With experience you may learn that you prefer the seat a
bit higher or lower than your hip bone and can quickly adjust the height when you unfold
your bicycle.
Seat height is adjusted by loosening the QR levers that retain the seat post. Once you
have adjusted the seat post extension, be sure to tighten these two levers.
WARNING:
If your seat post is retracted beyond the minimum insertion
mark, the seat post or frame may break, which could cause you to lose control
and fall. The minimum insertion point is stamped onto the seat from the bottom.
If your seat post is not long enough contact USAC WORLD, or your dealer, for
a longer seat post.
Most people prefer that the top of the saddle is horizontal, however some prefer it to tilt
down slightly. You may wish to adjust the position of the saddle on the seat post to fit your
personal preference. You do this by loosening the single bolt under the saddle with a 6mm
hex key. Once this bolt is loose you should be able to rotate the saddle and slide it fore/aft to
provide the best comfort. Once you have adjusted the seat position, be sure to tighten this
bolt.
WARNING:
After saddle adjustment, be sure to tighten the saddle clamp bolt
before riding. A loose saddle clamp could cause you to lose control and fall.
When the saddle clamp bolt is tight, the saddle should not move at all.
There are many different saddle designs, some for racing, some for comfort, some for light
weight. Your USAC STERNER is equipped with a relatively common saddle. However, you
may wish to exchange it at a bicycle shop for a different design to meet personal
preferences.
There is little handlebar height adjustment on the USAC STERNER. The standard height fits most
people. Especially tall riders may wish to replace the standard stem with a longer one.
Shorter riders may wish to replace the standard stem with a shorter one. A trained
bicycle mechanic can provide you with a variety of choices and properly fit the stem. It is
also possible for your dealer to fit especially short riders by cutting a little bit from the riser.
(Of course this is an irreversible action, so be sure you wish to do this before cutting metal.)
