Zipp's Service Course 70 XPLR. The bar's moniker, XPLR, exemplifies the desire to explore the world with an expanded definition of cycling on a drop bar bicycle- from paved roads onto gravel, mud, dirt, and even single track. The Service Course 70 XPLR help you go faster by placing your body, starting with your hands, in an optimal "comfort zone" position for hours of rough riding over mixed terrain. Today's riders demand a few things out of their cockpit, whether they are doing a two hour training ride from home or a 200 mile gravel adventure: comfort, control, and the ability to carry what they need. We met these needs by creating a bar with shallow and wide drops, specifically focusing on two crucial metrics-outsweep and flare.
