Zipp Service Course SL Stem +/-17

Is the Zipp Service Course SL Stem +/-17 the Right Fit? The Zipp Service Course SL Stem in +/-17° is machined from 7075 aluminum and engineered to the same 1.85 grams per Newton meter stiffness standard as the rest of the SL stem family, delivering no-flex performance at the bar-to-fork interface through hard sprints and fast descents. The +/-17° rise gives you a meaningful step up in bar height over the standard +/-6° version, making it the right call for riders who need to build stack into their cockpit without adding extra headset spacers or compromising stem length. Available in 70mm, 80mm, and 90mm lengths with a 31.8mm four-bolt faceplate, the SL Stem +/-17 works with any modern oversized handlebar and installs cleanly with standard hex tools. The combination of SL-grade stiffness and an intermediate rise angle makes this stem particularly useful for endurance road builds, riders transitioning from more upright positions toward a sportier fit, or anyone whose geometry calls for more hood height without going to an extreme rise. A precision cockpit component with real fit versatility built in.
