The overall riding position
Overall Tribar riding position
A torso to horizontal angle of 1° is optimal (note this is for a triathlon bike as this reduces frontal area and aids airflow over the body), this can be achieved by reducing the torso to lower body angle. However, an acute angle may also reduce pedalling effectiveness and power output.
Much of the rider weight is transferred through the upper arm. An upper arm to torso angle close to 90° with the shoulder directly above the elbow ensures that the weight is transferred through the humerus and skeletal structure. It also helps to get the torso (back) flatter and reduces the work required to support body weight.
If the angle is less than 90° the rider’s weight is shifted too far forward compromising bike handling.
An angle greater than 100° shifts the riders weight back onto the saddle which may result in discomfort and injury and also compromise bike handling.
Overall Drops riding position
In the drop position the saddle height and handlebar height should combine to give the rider a relatively flat back position with 7.5 cm to 10 cm between elbow and knee at the 3 o’clock position.
