Specialized's Dirt Bag is large enough to carry a tube, tire levers, a mini tool, a patch kit and more! Plus, it unzips and expands for even more carrying capacity. It's also water resistant and has an internal neoprene tool pocket to keep your tools from puncturing your spare tube. The Dirt Bag is securely held in place with handy hook-and-loop straps.
