The Road Tube Spool is a simple, compact system that'll carry everything you need to fix a flat without weighing you down. To do so, its design allows for a spare tube, with up to an 80mm valve stem, to be rolled-up without damaging the tube. Meanwhile, the Spool easily holds a lever, CO2 cartridge, and a valve head.

• Ingenious design allows a spare tube to be rolled up, while protecting the valve stem from rubbing a hole through the rubber.

• CO2 valve head and two-sided tire lever snap into place for compact and secure storage.

• Holds a single threaded 16g CO2 cartridge.

• Fits up to 80mm-long tube valve stems.

• Hook-and-loop strap holds everything securely in place.
