OUR NEW 700C HIGH PERFORMANCE GRAVEL TUBE. Removable core for riders that would like to add sealant to their tube or add an extender
Butane Black tubes feature a .73mm butyl rubber wall which is thinner than traditional tubes, and a light weight black 48mm valve stem with a removable core to reduce rotational weight and rolling resistance. The end result saves approximately 40g of weight per tube when compared to a standard tube.
35-42mm width to cover a wide range of tire sizes.
