Zipp’s sl speed stem represents the essence of carbon componentry. It’s stiff secure and light weight with a sleek design that compliments any bike. It’s a perfect addition to a mountain climber’s favorite feather-light road bike but it’s 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-toweight standards. The sl speed is available in six sizes ranging from 70 to 120mm to meet any rider’s fit needs. Includes stiff aluminum faceplate and titanium hardware torx® t25 heads for precise torque readings and ease of adjustment.
