The SLC2™ satisfies even the most demanding riders with a massively stiff handlebar that's clip-on compatible and weighs just 195g (Short & Shallow drops, 42cm). To get there, we started out by keeping more than 60 percent of the bar width at the same 31.8mm diameter as the clamp area. Then we strategically redesigned the carbon-laminate structure, adding strength around the clamp to handle clip-on extensions and stiffness to handle sprinting loads. Despite its stout characteristics, the SLC2 cuts no corners in terms of ride quality due to Zipp®'s vibration absorbing VCLC™ technology. The only Zipp carbon drop bar designed for clip-on extensions, the SLC2 is the perfect complement to the Vuka Alumina Clip with your choice of Vuka extensions.
