This is the Zipp Service Course SL Stem with a +/-6° rise. Your stem has to resist flexing during sprints and accelerations, clamp securely to the fork and handlebar, and support your weight over significant impacts. It’s a difficult job, but the Service Course SL stem is still able to combine strength, stiffness and reliability at a weight of only 135 grams (100mm). The Service Course SL's 3D-forged, 7075 series aluminum body paired with titanium Torx bolts delivers exceptional strength-to-weight ratio while allowing for smooth lines to complement the aesthetics of modern frames.
- Torx® head bolts that give precise torque readings while reducing the chance of getting stripped
