A bicycle rider's position on the bicycle is prompted by the need to reduce
the area of the body that comes into contact with the air. The more
aerodynamic the rider's position on the bicycle is, the less power the
bicyclist has to produce to achieve and/or maintain a given speed. If you've
ever ridden your bicycle from east Tucson up Mount Lemmon, you've likely
gotten caught in one of the many 'wind tunnels' on the way up the mountain.
At times like this, Tucson bicyclists become acutely aware of the power of
wind.
Bicycling shorts have always been fodder for numerous jokes. Of course, the
jokes come from those who do not understand the function these odd looking
shorts serve. First, the shorts are skin-tight to reduce the air resistance.
But the tight fit and 'slippery' fabrics keep the shorts from rubbing
against the bicyclist's skin. Along the shorts to constantly flap and rub
can create a very sore area, and even an open wound.
Of course, what may be the most desirable (and most picked on) element of
bicycling shorts is the padding. The padding is built into the seat of the
shorts. Because the bicycle is built in such an aerodynamic form, with
primary attention given to reduced weight, the bicycle seat is made to be as
slim as possible. This does not make it very comfortable to sit on. The
addition of padding in the bicycle shorts' seat offsets this lack of
'built-in' comfort in the original seat design.
