Description of ZIPP Service Course SL-OS 31.8 Stem – High-Polished Black
Selecting the correct stem is crucial to your fit, form and function on the bike. It needs to be stiff so you are not flexing away precious energy in sprints and accelerations. It must be reliable and strong but light. It has to adjust to your personal fit needs.
The all-new Zipp Service Course SL-OS Stem checks off all of those boxes. In a first for Zipp, this ±6° stem is compatible with “oversized” 1-1/4 inch steerer tubes used for instance by frame makers Giant and Canyon. For those riding standard 1-1/8 inch steerer tubes, the Service Course SL-OS offers addtional fit options with included shims allowing the stem to be adjusted for ±4° ±6° or ±8° angles. That helps you dial in your position on the bike like a pro.
Forged from high-strength 7075 series aluminium, this stem is lightweight and stiff with a 1.73g/nm stiffness to weight ratio for better control and responsiveness. Features titanium hardware and TORX® heads on all bolts for precision torque readings and ease of adjustment.
