Combining ergonomics, function, and sustainability, the GP1 BioKork has is a top-rated grip and a consumer favorite. The grip is made from 40% cork, sourced from sustainable forests in Portugal. This green, sustainable theme is echoed throughout the complete construction of the grip with an inner core made of a reinforced plastic utilizing natural fibers which makes up 20% of its mass. (Carbon bar compatible).
Problem: Excessive pressure on the sensitive areas of the hands result in numb fingers. Solution: With an anatomically optimized design, Ergon grips offer 100% contact with the hand surface area, versus traditional round grips, that offer only 60% contact.
Problem: Excessive curvature of the wrist leads to undesired kinks in the carpal tunnel nerve. This results in a burning pain in the hand or forearm. Solution: By correcting the hand position, the carpal tunnel nerve is relieved and pain is eliminated.
Since hand sizes vary from person to person, the GP Series and GS Series grips are offered in two sizes; Small and Large. These sizes refer to the gripping circumference. The Large size is a thicker grip, and the Small is a thinner grip. Two size options offer better hand closure around the grip surface. These size differences have a direct impact on the overall handling of the bike, as well as comfort.
