Q-Tubes offer a durable tube that has consistent wall diameters to ensure smooth rolling. The Presta valves themselves are removable so can use sealant, replace a damaged valve, on in the event you require a longer valve stem overall. The quality butyl material can be easily patched to keep the tube going after flatting. Choose size and diameter to suit your needs.
