Zipp Service Course SL road stem has been the benchmark alloy stem for some years now. It's a lightweight ally stem with 4 bolt fastening that grips the bar like no other.  

Black on black make for a fantastic looking cockpit when combined with any of the Zipp road handlebars 

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.
