Zipp first developed the Service Course SL stem for the fit and performance needs of pros. That goal of being pro grade has proven out over the past several seasons 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. Now, we take that pro-proven legacy and build on it with the redesigned Service Course SL stem.
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. To meet every rider’s fit needs, the stem is available in ±6° and ±17° angles and seven lengths from 70 to 130mm.
Features titanium hardware with TORX® heads on all bolts for precision torque readings and ease of adjustment. (More information below.)
