GP1 BioKork

GP1 BioKork

The GP1 BioKork provides ultimate ergonomics for the hand just as the rest of Ergon’s Performance Comfort series do, however the unique qualities of cork means that it is now antibacterial and hypoallergenic.

Cork’s natural damping qualities also make it an ideal grip material, and its now density mean the resulting grip is a lot lighter.

The GP1 BioKork uses 40% cork, sourced from sustainable forests in Portugal which is certified for its ecologically sound production. This ecological theme is continued throughout the rest of the grip.

The inner core is plastic reinforced using natural fibre, which make up 40% of its mass. In place of mineral oil, the gel in the palm section of the grip is vegetable oil based.

The clamp can also be 100% recycled. It is all a result of Ergon’s “GreenLab” initiative.

Ergon’s GreenLab initiative is about combining the core principles of ergonomics and performance with ecologically aware practices.

Introduced in 2010, and for 2011, the GreenLab initiative has played an important role in the Ergon Development Department and the results of that can be seen starting with the innovations in the last two years. Ergon’s extensive grip assortment is now presented with completely reworked and re-invented packaging.

This uses as little material as possible to achieve our aims, and much of the material used is recycled. The sustainability of the packaging was a key factor, and that the packaging can be recycled after use, and uses as few components as possible, a priority – minimising the environmental impact. The result of this new packaging quest is so innovative that it has already won the coveted German DesignPlus packaging prize. A further example is the GP1, new GR2 BioKork and GC3 BioKork grips. Once again, it is Ergon setting the standards using the most innovative materials and technology to achieve our aims.

The Size Difference.

As hand size is different from person to person, Ergon manufactures the GP, GS and GA ranges in two sizes - Small and Large. This difference is in the diameter of the grip. The reason for this is that a larger hand is better able to grip a larger grip with less stress and effort.

This is the same in reverse for small grip. A smaller hand needs a smaller grip to allow the hand to close around it. Of course, this is all also down to personal preference.
