Zipp s Service Course range is designed to offer high performance without breaking the bank. The Service Course stem is a great blend of strength, stiffness, reliability, low weight, good looks and a price tag that doesn t make you wince. The redesigned Service Course stem features a new body and faceplate design and is constructed from 6061 aluminium for an improved stiffness to weight ratio, while also offering a sharp new look that syncs beautifully with modern frame designs and integrates perfectly with Zipp s Service Course Handlebars and Seat posts. Available in a wide range of sizes it is easy to get the perfect length for your bike, while the stainless steel Torx T25 hardware is less likely to strip and won t rust over time. A simple stem it may be, but the Zipp Service Course offers a lot in a well-designed and great value package.High Performance Road Bike StemNew Faceplate And Body DesignLightweight 6061 Aluminium ConstructionStainless Steel Torx T25 Hardware31.8mm Handlebar
