Butane Black tubes feature a .73mm butyl rubber wall which is thinner than traditional tubes, and a lighter black aluminum valve stem with a removable core to reduce rotational weight and rolling resistance. The end result saves approximately 20g of weight per tube when compared to a standard tube.
