Ergon’s original and ground breaking GP1 continues to set standards. Offering optimal pressure distribution and available in two sizes, it features a forged aluminum clamp for fast and secure installation. Adjustment of the support platform is achieved by simply loosening the clamp bolt and positioning the grip to the desired neutral position.

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.
