Schwalbe Aerothan No. 21E Inner Tube - 27.5" | MTB

Schwalbe Aerothan No. 21E Inner Tube - 27.5" | MTB

Uniquely light, extremely stable: The tube revolution made of Aerothan

Aerothan is a material that completely redefines the bicycle inner tube: extremely light,
highly puncture-resistant and designed for the lowest rolling resistance.

The revolutionary tube made of Aerothan achieves previously unattained peak values for elasticity, weight and puncture resistance. Especially for road, MTB and trekking bikes.

Aerothan Tube - The facts

  • Consistently light up to the valve - around 40% lighter than a comparable Schwalbe Extralight tube
  • Puncture safety redefined - the material prevents sudden loss of air
  • Minimum rolling resistance - maximum driving dynamics
  • Valve length: 40mm
  • 100% recyclable
  • Extremely heat-resistant - approved for rim brakes
  • Stable handling - even at low air pressures
  • Made in Germany


When it comes to road cycling with tube, the Aerothan Tube Race is the first choice. Because it convinces with low rolling resistance and dynamic, smooth riding dynamics. In comparison
to butyl tubing, a weight saving of 100 grams or more can be achieved for the entire bike. The Aerothan Tube Race can be relied upon not only for excellent puncture protection, but also on downhill rides: Even during several emergency braking maneuvers with rim brakes in quick succession, it remains absolutely heat-resistant.


The Aerothan Tube MTB is just as resistant to snakebites as it is to sidewall damage - the extreme robustness of the material ensures this. For cross country and marathon use, the amazingly low weight and low rolling resistance show their advantages. Even on challenging trails, this tube never lets anyone down: Because the Aerothan Tube MTB remains extremely dimensionally stable even at low air pressures, you always have the bike reliably under control.


The Aerothan Tube Allround is the extremely light and absolutely reliable high-end tube for city and tour. Compared to Schwalbe standard tubes it makes the bike about 180 grams lighter - together with the low rolling resistance it guarantees much more riding fun. You can also rely on its puncture protection for longer rides in the countryside. Even if you forget to pump up the bike, the Aerothan Tube Allround does not take it badly: It remains dimensionally stable even at low air pressure and keeps the bike safely on track.
