The latest in aero bar technology is small, light, simple, and very effective! The Gnarwal mounts to the center of the loop portion of the Jones Loop H-Bar, and gives a solid hand-hold when resting your forarms across the crossbar and loop portions of that bar for a great aero position. Beautifully machined in the USA, the clamp allows the extension tube to be swapped or replaced. The extension tube can be wrapped with bar tape or used with a standard grip (not included). It also becomes a great place to mount a computer! Many will want to double-wrap the crossbar as well as wrapping the loop portion of their H-Bars to maximize comfort in the aero position.
