Zipp: STRENGTH AND STYLE The Service Course® stem delivers all you look for in a stem—strength, stiffness, reliability, a precise fit and distinctive look. The Service Course stem offers a faceplate and body design for greater stiffness and easier installation. It’s high performance and high value. The Service Course Stem’s shape and 3D-forged construction results in an improved stiffness-to-weight-ratio. The stem design, along with distinctive graphics, also complement the aesthetics of modern frames. Made from 6061 aluminium, the stem resists flexing during sprints and accelerations.FEATURESFaceplate and body geometry designed for greater stiffness and easier installationBead blast black finish with updated Zipp cosmetics±6° and ±25° rise stem availableLeading Stiffness-to-weightSecure with four bolt faceplate using Torx T25 bolt heads.Lifetime warrantyZipp Quickview integrated compute mount available separately SPECIFICATIONSMaterial (SP/ST): Al-6061Length (ST): 105mm, 120mm, 75mm, 90mmStem angle/rise: 25 degreesClamp diam: 31.8mmSteerer clamp diameter: 1-1/8 inColour/finish (ST): Bead Blast BlackHardware: Steel
