Schwalbe inner tubes perform!
Schwalbe bicycle inner tubes are renowned for quality. Once vulcanized, all Schwalbe bicycle inner tubes are inflated and stored for 24 hours in order to test for air pressure retention. Afterwards each, individual tube undergoes a careful visual inspection. This special quality control helps prevent unpleasant surprises.
Schwalbe bicycle inner tubes have a high elasticity which mean one inner tube can be used for many tire sizes which vouches for the tube's quality.
All the Schraeder and Presta valve styles are nickel plated and threaded and valve inserts are replaceable.
