Zipp first developed the Service Course SL stem for the fit and performance needs of pro cyclists. That goal of being pro-grade has proven out over the years as the stem became a mainstay in the pro peloton and cyclocross circuit, being ridden to victory in Paris-Roubaix and the Vuelta a España and many other races.
The Service Course SL Stem, crafted from 7075 aluminum, features a redesigned shape that’s strong and lightweight, resulting in a best-in-class 1.85 grams per newton meter of stiffness. That results in no-flex sprints and accelerations. Finishing touch includes titanium hardware with TORX® heads on all bolts for precision torque readings and ease of adjustment.
