The Zipp SL Sprint Stem has been specifically designed to provide the ultimate performance for Pro Road riders. Zipp used feedback from Grand Tour sprinters to create a stem that has the stiffness to handle their unrelenting demands, yet with as low a weight as possible. It even features an aerodynamically shaped faceplate that smoothly integrates with the stem's body. The SL Sprint has everything you need to make sure you out-perform the opposition.
