Zipp – Service Course SL Stem
The Zipp Service Course SL Stem is an aluminium constructed stem with a best in class weight to stiffness ratio. To better fit every rider, it is available in ±6º and ±17º and seven lengths from 70mm to 130mm (140mm and 150mm are available for the ±6º stem as well). This allows it to be a popular stem for all of the bike fits that we do. Zipp has now released the stem with updated graphics to match the graphics on their wheels and handlebars. It is also compatible with the new QuickView mount using the Service Course variant. Zipp also provides a lifetime warranty with the product.
