Schwalbe 21 Air Plus Inner Tube for 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.

Good to know: The valve of all Schwalbe tubes with Presta valves can be unscrewed, e.g. for valve extensions or for filling with tyre sealant.

AV / Schrader 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.
