The 100% recycled Shifty Grips are designed as an ergonomic solution to anyone riding with a one-by front crank with a Gripshift™ or other twist shift style rear shifters. The left side is designed as a standard 132mm closed end grip with a clamping bolt to fix your grips into place. The right side is shorter (only 92mm) to accommodate twist style grips. It also features the same closed end grip and clamping bolt design. The Shifty Grips utilize an ergonomic shape to keep your hands “happy” by reducing stress on the palm and creating a comfortable point of contact between you and your bike. The non-slip rub texture works great in all-weather.
