Zipp Service Course 70 XPLR Drop Handlebar - Aluminum 31.8mm 46cm Silver. 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.

Bar drops provide a wider balanced and secure position with drops that are about 6cm wider than the hoods position for technical or intense riding

The 70 XPLR also features an ergonomic top with an extended 100mm clamping area for computer mounts aero-extensions bags and whatever else you may need for the long haul
