Schwalbe 7 Air Plus Tube for 20"

Schwalbe's Air Plus Tube 7 for 20" 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

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 tubes exceptionally robust against punctures and snake bites.
