Zipp: STRENGTH AND STYLE On today’s road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored handlebar color is available on the Zipp Service Course stem. Since the introduction of our line of Service Course and Service Course SL components we’ve had amazing success with our pro level athletes in all disciplines. While the successes have been proving, we have also drawn from their feedback. We not only learned how and why athletes make their equipment choices, but how our manufacturing methods and materials affect product performance. With new knowledge as well as new engineering, we are proud to introduce our completely redesigned line of Service Course and Service Course SL stems and seatposts.FEATURESDistinctive silver finishMore options for better fit6° and 25° rise stem availableLeading Stiffness-to-weightNew faceplace and body geometry for greater stiffness and easier installation SPECIFICATIONSMaterial (SP/ST): Al-6061Length (ST): 60mm, 70mm, 75mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mmStem angle/rise: 6 degreesClamp diam: 31.8mmSteerer clamp diameter: 1-1/8 inColor/finish (ST): n/aHardware: Steel
