Butane tubes feature a .73mm thick butyl rubber tube which is thinner than traditional tubes, and a lighter aluminum valve stem to reduce rotational weight. The end result saves up to 25g of weight per tube (depending on valve length) when compared
to a standard tube.
BUTANE TUBES CAN REDUCE ROTATIONAL WEIGHT BY 50g.
(AS MUCH AS 25g PER TUBE DEPENDING ON VALVE LENGTH)
