Why Riders Choose the Zipp Service Course Stem +/-25

The Zipp Service Course Stem delivers the combination of strength, stiffness, and precise fit that riders expect from Zipp at a price that makes it accessible to any build. Its redesigned faceplate and body geometry improve stiffness and simplify bar installation over earlier iterations, resulting in a cleaner cockpit and more confidence under hard efforts. The +/-25° rise covers a wide fit range, making it ideal for riders who need significant bar height adjustment, are building a more upright endurance position, or are fitting a bike with lower stack height.

Available in 75mm and 90mm lengths to match your cockpit geometry, this stem pairs with any modern 31.8mm oversized handlebar and installs cleanly without fuss. The four-bolt aluminum faceplate distributes clamping force evenly for secure bar retention across training and racing. For riders who want Zipp cockpit quality without the SL premium, the Service Course Stem is a straightforward, dependable upgrade that delivers well above its price.
