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 result of this innovation and these experiences is the 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 as well as a 140mm length for the ±6° stem only.
Features titanium hardware with TORX® heads on all bolts for precision torque readings and ease of adjustment.
