The Zipp Service Course SL Handlebar gives you the strength and stiffness of aluminum, with a weight that hovers in the carbon fiber range. Available in both a traditional and short and shallow bend, the Service Course SL features a drop angle of only 20 degrees, allowing riders to place shift levers higher on the bend without hindering the smooth transition from the hoods to drops. The drops also angle out 2 degrees to make long days in the saddle a little more comfortable.
