Seat Post

The seat post is designed specifically for the STERNER and is an integral part of the overall 
frame structure.  Use of a different seat post may result in substantially shortened frame life 
and will void your frame warranty.  Seat posts approved for use with your frame are 
available from USAC WORLD's website or your dealer.

Please ensure that both seat post QR levers are tight.  To verify that a clamp is tight, release 
the other clamp and check that the seat can not be easily twisted relative to the frame.

A minimum insertion point is stamped onto the seat post.  The seat post must be inserted to 
at least this point.  If your seat post is not long enough contact USAC WORLD, or your dealer, for 
a longer seat post.

Braking

Your bike is equipped with front and rear brakes.  The right brake lever is for the rear brake. 
The left brake lever is for the front brake.  Generally you should apply both brake levers 
gradually to stop.

WARNING

: Sudden or excessive application of the front brake may pitch the 

rider over the handlebars, causing serious injury or death.

WARNING

: In wet weather conditions, you will need to increase the distance 

needed to stop safely.  Anticipate the extra distance you will need, ride slowly 
and carefully.  Squeeze your brake levers slowly and with gradual pressure to 
avoid skidding or loss of control.  The same caution should be observed on 
loose gravel or dirt.  Failure to be cautious during wet or other severe road 
conditions may result in a serious accident.

WARNING

: Worn-out brake pads can result in a lack of braking function.  A 

lack of braking could cause you to loose control or fall.  Falls can result in 
serious injury or even death.  Check the brakes for proper function before each 
ride.
