Abstract
Aerodynamic enhancements and modules for cycling and other speed sports such as skating and skiing include in one embodiment a wind drag reducer including two tapered arm/leg wedges. For cycling the the tapered wedges which are held in position by a stretch fabric sleeve, are worn on the upper arm area. For speedskating the tapered wedges are placed around the calf and a slightly modified wedge is attached to the heel of the speed skating boot. Another type of wind drag reducer includes a contoured rear spoiler board which is strapped to the back of a cyclist. An aerodynamic module to improve laminar air flow according to another embodiment includes a pod with a forwardly protruding nose-cone shaped front surface. The pod is held in position around the cyclist by a stretch fabric sleeve and strap arrangement.
