Schwalbe Inner Tube 21+ Air Plus for 27.5" / 27.5+

Schwalbe's Air Plus Inner Tube 21 for 27.5+ tyres is characterised by its special puncture resistance and air retention and is therefore also suitable for e-bikes and cargo bikes. This is made possible by a 70% higher wall thickness and a high proportion of pure butyl rubber.

Valve Information

Tubes are available with various valve types.
Choosing a valve is dependent on application and the rim's valve hole diameter.

SV / Presta Valve:

Technology:

Air Plus:
Schwalbe's Air Plus tubes hold the air much longer than other tubes due to their high proportion of pure butyl rubber, so that you need to re-pump less often.

Puncture Protection:
70% more wall thickness makes the Air Plus inner tubes exceptionally robust against punctures and snake bites.
