The Blackburn Outpost Corner Bag makes clever use of the unused space behind your bike's head tube. Designed with a rigid structure, it keeps its shape while securely holding ride essentials like a CO2 cartridge, spare tube, and tools. Its compact form stays tucked out of the way, so it won't interfere with pedaling or steering. Water-resistant materials add extra protection from road spray and light rain. Perfect for riders who want efficient, accessible storage without adding bulk to their setup.
