Zipp Service Course SL Stem
Your stem has to resist flexing during sprints and accelerations, clamp securely to the fork and handlebar, and support your weight over significant impacts. Itâ€™s a difficult job, but the Service CourseÂ® SL stem is still able to combine strength, stiffness and reliability at a weight of only 120 grams (100 mm).
The Service Course SL has high-strength, 3D-forged construction, 7075 series aluminum and titanium bolts to deliver an exceptional strength-to-weight ratio while allowing for smooth lines to complement the aesthetics of modern frames.
We make our Service Course SL stems in seven lengths (70 mm to 130 mm in 10 mm increments) and two angles ( /- 6 degrees and /- 17 degrees) to meet any riderâ€™s fitting needs.
We replaced the stainless steel bolts with titanium ones and use TORXÂ® heads on all bolts for precision torque readings and ease of adjustment.
Every piece in the Service Course SL line is available in the standard gloss black with white logos, as well as a new Beyond Black color scheme with laser-etched black logos for a stealthy look.
