Zipp’s Service Course SL Stem (ST-SC-SL-B2), crafted from 7075 aluminum, features a 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 lengths from 70 to 130mm as well as a 140 & 150mm lengths for the ±6° stem only. This stem is a favorite of Zipp ambassadors and pro athletes.
