Gel is a specific kind of closed-cell foam. The air bubbles in this foam are packed at a pressure which is higher than the normal. This is what makes it viscous. It is the viscosity of gel that molds the saddle cover to the back so that there are no painful pressure points. Gel saddle covers were first used in the eighties.

A gel saddle cover is very comfortable for all riders because it is custom made to suit not only the rider but also takes into consideration the kind of riding that the rider wants to do. A gel saddle cover for a man would have a 35 mm central depression that would relieve the pressure from the sensitive areas thereby not becoming a health hazard.

A gel saddle cover for a woman would have a narrower depression, avoiding any kind of compression of the tissues at the centre-point of the saddle. The gel saddle cover is wider in the rear and completely cutaway through the nose of the saddle and also the mid-section. This allows for the pressure to be evenly distributed, and provides support to the sensitive areas.

The gel is a little stiff at the rear so that you get the power you need to pedal your bike. The biker cannot choose the terrain where he is going to ride. The gel saddle cover offers sufficient cushioning against rough and uneven road surfaces. Superior quality gel neither gets deformed nor loses its viscosity no matter how old the gel saddle cover is or how much it has been used.

There is a flexible nylon base on the gel saddle cover that absorbs shocks. A gel saddle cover which has longer and larger cutaway might also feature an inverted v-wing in the rear. This allows for greater flexibility and offers relief to the tailbone. If the rear end of the gel saddle bike is raised, it gives the rider the necessary support for power climbs.
