The Specialized 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 can easily hold a lever, CO2 cartridge, and a valve head. The Patent-pending design allows the spare tube to be rolled up while protecting 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.
