Zipp Service Course SL 80mm 17 Stem Beyond Black

The ultimate in performance and technology

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 Espaa 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 aluminium, features a redesigned shape thats 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 riders 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.

Available in two colour schemes: High-polished Black with Silver Laser-Etched Graphics or Beyond Black anodized with black logos.
