The X-Lab Super Wing is an aluminum version of the carbon wing and, with a multitude of storage options and bottle cage configurations, this is one of the most versatile systems you will find. The X-Lab Super Wing is also a great hydration system to keep the drag down to a minimum. You can use the single bottle cage on the rear of the Super Wing or two on each side. Use the optional XNut to hold your CO2 cartridges and drop in the mini bag for tires and tubes. There are various mounting holes on the wing so you can get your hydration system set up the way you want it.
