Grips can be made from lots of materials: foam, rubber, plastics, and our favorite - specialized polymers. Naturally, polymers are the most expensive and there's only one place to get the good stuff - from Ohio. But after all kinds of testing, from the heat of Death Valley to the extreme cold of the Northeast, the Spider Grip design team knew that advanced polymers were the only thing for a state of the art grip.
But these guys didn't stop with using the best materials - they created a design using varied densities of polymers - taking advantage of the flexibility of the material and its diverse advantages.
Isolated Secondary Layer - To take advantage of the features of softer polymers, the Spider Grips design team placed a second layer on the grip. This created a boundary layer in the middle of the grip to reflect and dissipate vibration from the innermost layer. The softer outer layer also reflects and absorbs vibration, and it is completely separate from the motorcycle handlebar. This isolated layer of polymer seriously reduces the vibration making it to the rider's hand. The Spider Grip was designed to be the "quietest" motorcycle grip on the market.
Multi-faceted Surface Area - After taking a good hard look at classic motorcycle grips, the Spider Grip design team realized that the 25-year-old waffle grip was, well, 25 years old. They considered many different designs before settling on a shape based on the inside of a cupped hand. This multi-facted vario shape is very comfortable and without ribs the riders got fewer blisters. Another benefit of the vario pattern is that it offers maximum contact area. This gives more rider control, and combined with the soft polymer that makes the Spider Grip sticky, it is easier to ride with a lighter touch. The less a rider uses "Death Grip", the longer he can ride without the dreaded arm-pump.
Being the fun guys they are, the Spider guys insisted on colors. Lots of colors. One guy on Honda wanted yellow, another red, the Kawasaki rider had to have his green, and of course Mr. KTM wanted orange. Before it was over the grips were spec'ed out in those plus Yamaha Blue and three different black and gray combinations.
After 18 months of intense work, testing and rider feedback, the Spider Grip design team knew that they had a design that sent everything else in the market right over their bars.
