It's time to re-think packaging for a tube, keep it simple and reduce waste! The tapered design means you never have to fuss with unboxing; simply put your tube in your saddle bag or jersey pocket and start riding. The WheelSmith tube packaging is made of out Tyvek- this adhesive panel is designed to be used as a tire boot! Every tube is equipped with a glue-less patch-kit! Tubes are made from a high quality butyl compound, each tube is pre-inflated for 24hours prior to packaging to ensure there are no leaks or faults in the seams.
