We never know exactly what will happen on the trail, so we trust the Crank Brothers S. O. S. BC18 Bottle Cage Kit to provide mechanical support for our ride. This kit attaches easily to our frame, giving us easy access to our water bottle and several of our go-to tools, including a CO2 head, T25 and T10 torx tools, flat screwdriver, tire plug and 4x plugs, tire lever, chain tool, valve core tool, spoke wrenches (0,1,2), and 2, 2. 5, 3, 4, 5, 6 hex tools + 8mm adapter bit.
