Pelvic Bone Pain

  

Probably the most challenging sources of seat discomfort to conquer is painful pelvic bones.  As shown in the diagrams, these bones, called the ischium, which are part of our pelvic structure, carry the bulk of a rider's weight when sitting on a seat. Some seats are so uncomfortable that the pelvic bones can start hurting within 30 minutes after the start of a ride. To get an idea of how much the pelvic bones, or ischium, are involved in sitting and riding, archeologists exploring ancient Chinese grave sites supposedly can determine ages of cavalry soldiers based on how much their pelvic bones are worn.

 

 

Tailbone Pain                           

 

 

The tailbone is actually the final segment of the vertebral column (see the picture below). It is attached to the sacrum by a fibrocartilaginous joint (the sacrococcygeal joint) that allows it to move a bit. Because this joint is flexible, riding on a bike can cause it to move; and if the joint becomes irritated, this can be one of the causes of pain. If you've ever experienced tailbone (coccyx) pain, you know how debilitating it can be. In some cases, it's almost impossible to sit for more than a brief period of time without serious pain.  Causes of tailbone pain can be injuries, too much sitting, and even childbirth. Typically, it takes care of itself. The worst case scenarios result in the surgical removal of the tailbone (coccygectomy).

Notice that the picture below shows a more upright cruiser or sport-touring riding position. This position typically causes more pressure to be placed on the coccyx. The feet are forward, thus not supporting the downward pressure on the back. The back is also relatively straight, which places more bending pressure on the coccyx. For most riders, this isn't a problem. However, for those with tailbone or coccyx pain, this situation can be agony. 

 

 

Our gels help to alleviate these pressure points and problem areas by reducing vibration and making your seat more comfortable.                                                   
  • Redistributes weight over a larger surface area.
  • Particularly effective in a fixed seating position.
  • Reduces high-pressure points or "Hot Spots".
  • Dissipates weight concentrated by hip joints.
  • Increases blood flow previously restricted by compression of muscle.

 

 

By evenly distributing your weight across the surface of the seat, gel absorbs and elminates the extra pressure that is normally experienced at hip bones and the tail bone. These pressure points or "hot spots" create a loss of blood flow, causing discomfort. By increasing circulation, comfort is enhanced. 

 

Our viscoelastic dry polymer seat inserts will never harden or leak. Our polymer inserts are silicone-free and leave no film or residue that can destroy seat materials. They stop "numb butt", reduce rider fatigue and shorten recovery time on very long rides.
