Wolf Tooth's EnCase Handlebar Storage Sleeves provide a discreet and secure location for all the tools needed for trail or roadside repair. The sleeve's engineered design and rubber material keep the EnCase tools securely in place and free of rattling, while at the same time protecting the tools from dirt and moisture. With extra space in the bar plugs to store a presta-to-schrader adapter and valve core, or a master link for quick chain repairs, this nifty tool is all you'll ever need for most rides.
