Compact, secure, and convenient, the Blackburn Big Switch Wrap is your ride-along tool kit that sits neatly under your seat to help you fix just about any issue during the ride. This burly nylon pouch comes with and organizes Blackburn's Big Switch tool kit, which is designed to field fix everything related to your drive train, wheels, or brakes, whether you use the disc-pad spreader to ride drag-free or the chainbreaker tool to pop a pin out and remove a chainlink. Blackburn's ingenious design securely attaches the Wrap underneath your saddle, and then when opened, the tool kit hangs from your saddle so you can grab what you need without spreading it all on the ground and possibly losing tools. The Wrap features specific sleeves for an inner tube, up to a 20g CO2 cartridge, and a tire lever, and even includes a stash for your I. D., credit card, and cash when you don't want your pockets weighed down.
