The CZ Control features a semi-ergonomic shape that replicates the natural interaction of your hand with the handlebar. We used pressure-mapping technology to precisely determine where pressure is distributed on the grips, then increased support in those areas while conforming to the natural shape of your hand. The result is a shape that prevents numbness and increases overall comfort. The CZ Control features a tapered inner sleeve that eliminates the twisting that often occurs with other ergonomic grips. Balanced The CZ Control Grip is our balanced, semi-ergonomic grip that gently conforms to your hand, providing better control over the stick while relieving pressure that causes numbness in your hands. Single clamp CZ Control features a single-clamp mechanism that provides a secure and stable grip, making them less susceptible to sliding or twisting. Tapered inner sleeve Tapered, with less rubber on one end and more rubber on the other. It's all about greater comfort. More comfort means longer rides, which ultimately makes people on bikes happier. We call that a win, win, win!
