Your stem has to resist flexing during sprints and accelerations, clamp securely to the fork and handlebar, and support your weight over significant impacts. It’s a difficult job, but the new Service Course stem is still able to combine strength, stiffness, and reliability at a weight of 130 grams (100mm). High-strength 3D-forged construction and 7075 aluminum deliver an exceptional strength-to-weight ratio while allowing for smooth lines to complement the aesthetics of modern frames. During production, we take extra steps to ensure precise length and alignment across a range of fourteen sizes to meet any rider’s fitting needs.Weight (100mm) 130g Sizes 70,80,90,100,110,120,130 Clamp Diameter 31.8mm Angle 6 / 17 Steer tube diameter 11/8 Stack height 42mm Clamp width 40mm Clamp torque 4Nm.
