• 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.
