The CZ Control features a semi-ergonomic shape that mirrors how a hand naturally interacts with the handlebar. WTB used pressure mapping technology to precisely determine where pressure is distributed on the grips and then increased support in those areas while also conforming to the natural shape of the hand. This results in a shape that prevents numbness and increases overall comfort. The CZ Control features a tapered internal sleeve to eliminate the twisting that often occurs with other ergonomic grips.Tapered internal sleeve to create a snug fit that eliminates twisting at the end of the gripControl Category - balance between softness and bar feelSoft Rubber / anti-slip compoundSingle inboard clamp to keep the grips secure with a soft compound enclosed rubber endSemi-ergonomic shape distributors pressure away from areas causing numbness but designed in a watt to keep you in controlPressure relief in the thumb area
