Zipps SL Speed stem represents the essence of carbon componentry. Its stiff, secure and light weight with a sleek design that compliments any bike. Its a perfect addition to a mountain climbers favorite feather-light road bike, but its tough enough to tackle gravel and cyclocross. Designed using SRAM Exogram technology, found in SRAM RED cranks, the new SL Speed Stem weighs just 123g (100mm) while exceeding our stiffness-to-weight standards. Zipp set a new standard of performance and style in 2013 with the introduction of the sprinters favorite carbon SL Sprint stem. Now the SL Speed stem broadens our carbon offerings with a light weight 6 carbon stem. The SL Speed is available in six sizes ranging from 70 to 120mm to meet any riders fit needs. Includes stiff aluminum faceplate and titanium hardware Torx T25 heads for precise torque readings and ease of adjustment.
