Product information "SCHWALBE AEROTHAN TUBE 27.5" MTB"
No. 21E. For bicycle tires in size 27.5" inch (ETRTO 54/62-584).
The Schwalbe Aerothan Tube MTB is just as puncture-resistant against snakebites as it is against sidewall damage - thanks to the extreme robustness of the material. For cross-country and marathon use, the amazingly low weight and low rolling resistance really come into their own. Even on demanding trails, this tube will never let you down: because the Aerothan Tube MTB remains extremely dimensionally stable even at low air pressures, you always have a reliable grip on your bike.
Aerothan tubes are made of 100% thermoplastic polyurethane (TPU) (including the valve) and are therefore fully recyclable.
