Zipp Service Course SL Stem +/-6 Degree

The Zipp Service Course SL Stem +/-6 Degree is built for riders who take their fit seriously — a high-grade aluminium stem designed to deliver a clean, stiff connection between your hands and your front wheel without unnecessary weight. Developed with input from professional riders across disciplines, it offers the kind of reliable, no-compromise performance that suits everything from long training days to race day.

The +/-6 degree rise gives you meaningful flexibility in dialling your position, whether you're chasing a lower, more aggressive setup or need a touch more height for longer efforts. Nine length options — from 70mm to 150mm — mean there's a configuration to suit a wide range of riders and frame geometries. The 1 1/8-inch steerer clamp keeps it compatible with the vast majority of road forks, and a standard 31.8mm bar clamp covers most modern handlebars.
