Organic: 40 percent cork
The BioKork version of our successful GP series combines ergonomics, sustainability and a comfortable feel consisting of 40% cork material. The material comes from organic farming in Portugal and meets strict ecological guidelines. In the inner support, 20 percent of the plastic is replaced by grass fibres.
When riding, your hands support a lot of your upper body weight on the handlebars, placing high pressure on a relatively small grip area. In many cases this pinches the extremely sensitive ulnar nerve that runs near the base of the palm near the pinky and close to the skin’s surface – often causing numbness. The wing grip increases the hand’s supporting area by distributing pressure over a wider surface and thereby preventing discomfort.
If your wrist is bent too much for too long, nerves, tendons and blood vessels are compressed. The result is the carpal tunnel channel is constricted, which could damage the median nerve. Long rides and fatigue make it even harder for the rider to maintain a correct and healthy posture. The wing design of our GP grips gives the hand more support and automatically puts the wrist into a more ergonomic position, preventing numbness, tingling and pain.
Two sizes – for individualized control
In order to help you maintain perfect control over your bike, your hands should not completely envelop the grip, which is why Ergon offers many grips in two size diameters – Small and Large. The difference refers to the grip width (hand size), meaning a larger hand will have a more positive fit on a thicker grip, while a smaller hand is better fit to a smaller grip. For hand/glove sizes 6.5 to 8.5 we recommend Small, for 8.5 to 10.5 Large usually is better.
Locked down for safety
The GP Series clamping system is extremely secure and easy to mount. Each grip is tightened with only one bolt to reliably secure its position and to prevent twisting. Another important safety feature is that Ergon’s aluminum clamps are cold forged and not extruded – resulting in a much stronger structure. GP grip versions featuring lightweight bar ends – made of glass-fiber-composite and with grippy rubber inlays – deliver additional hand positions for more comfort.
Fits any type of shifting mechanism
Some models of our GP series, including the GP1, are available in special versions for different shifting capabilities. For a regular shifting, both grips are the same length. The version for Gripshift® or Dual-Twist-Shift twist-grip shifts includes two shortened grips, for Rohloff®, Nexus® and Single-Twist-Shift only the grip on the right side is shortened.
It’s in the mix
Minimum friction-maximum comfort: While riding Ergon’s super soft, UV resistant, long life rubber compound with specific surface texture features provide a confident grip. At the same time, they’re pleasing to the touch–noticeably elevating your riding enjoyment.
