Zipp – Service Course Stem
This Zipp Service Course stem is offered in two angles and ten lengths, all allowing you to position your handlebars optimally. Constructed from 6061 aluminium, the stem resists flexing during sprints and power loads. The stem has updated graphics to better compliment the aesthetics of modern frames. Similarly, Zipp has managed to improve the stiffness-weight ratio, through the use of an altered shape and a 3D-forged construction process.
This new shape for the Service Course stem also provides easier installation and more strength, making this stem a better fit for your bike.
