Make use of the unused open spaces on your hardtail or full suspension bike for storage, with Blackburn's Outpost Corner Bag. This rigid bag fills in the gap behind your headtube by strapping it to the top tube and down tube with the included straps and daisy chains. Its adjustable mounting system allows fitment to almost any bike and the internal mesh pockets and loops make it perfect for storing CO2's, a tube, and tools. Carry these items on the bike and get them off your back. And with most of us these days rocking dropper posts, no one wants a bag cinched to a telescoping post and buzzing your tire when the post is dropped. An outer mesh pocket can carry a lightweight jacket or serve as storage for spent energy food wrappers. The water-resistant material protects items inside against the elements and the drawstring cinches and loosens with one hand, streamlining the bag.
