The Aerothan Tube MTB is just as resistant to snake bites as it is to side wall damage thanks to the extremely robust material. In cross-country and marathon, a surprisingly low weight and low rolling resistance are great advantages. Even on challenging trails, this tube never gives up on you: Thanks to the exceptional form stability of the Aerothan Tube MTB, even at low air pressures, you always keep control of your bike. Aerothan tubes consist of 100% thermoplastic polyurethane (TPU), including the valve, and are therefore fully recyclable.
