Zipp set out with one clear goal – design the best-performing carbon stem. Ever. The SL Sprint is optimized for the stiffness required by pro road sprinters, while still being light weight. Just as cyclists maximize performance by being as light, but as powerful as possible, the SL Sprint Stem strikes the ideal balance of stiffness and lightweight to deliver responsive handling without wasting a single watt. The stem weighs in at just 1.8g per newton meter of stiffness. How’d we do that? The SL Sprint was designed using SRAM’s Exogram technology, the same used in the ultra light and strong SRAM RED cranks. The SL Sprint was designed with feedback from top pros to meet the unrelenting demands of Grand Tour sprinters. Zipp also tapped into expertise gained from its pioneering carbon stems and exhaustively researched the marketplace to create the SL Sprint Stem. The SL Sprint comes with its own stem cap that’s designed to be aerodynamically efficient by blending into the stem body. Available in six sizes ranging from 90 to 140mm to meet any rider’s fit needs. Includes stiff aluminum faceplate and steel Torx T25 bolts for precise torque readings and ease of adjustment. Available in Matte White and Matte Black finishes.
