The SL Sprint 12 Degree 1-1/8 Carbon Stem from Zipp had one main goal, to be the best performing carbon stem. Ever. It does that by having the highest stiffness-to-weight ratio of any stem on the market. It has an amazing 1.8g/Nm stiffness which has been achieved by using SRAM’s Exogram technology to design it, the same technology which helped design the ultra light and strong SRAM Red cranks. Just like a cyclist optimises performance by being as light but as powerful as possible, the SL stem is an ideal balance of stiffness and lightweight, to give the optimum responsiveness without wasting a single watt. The stem comes with its own cap that has been designed to be aerodynamically efficient by blending into the stem body. The stem’s faceplate is made from aluminium for stiffness and steel torx T25 bolts for precise torque readings and ease of adjustment. Available in Black/White only in 90, 100, 110, 120, 130 or 140mm.
