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 the oversized 1-1/4 inch steerer tubes used by frame makers Giant® and Canyon®. For those riding standard 1-1/8 inch steerer tubes, the Service Course SL-OS offers new fit options with included shims allowing the stem to be adjusted for ±4° ±6° or ±8° angles. The stem also is available in seven lengths from 70 to 130mm. All that helps you dial in your position on the bike like a pro.
Forged from high-strength 7075 series aluminum, 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. (More information below.)
