Fits 700x37-47c and 40-635 tires.

Schwalbe Air Plus is extra powerful and made from recycled material from other tube that have been discarded.

When a tube is punctured, it is often replaced with a new one, but Schwalbe will give new life to all these otherwise useless tube.

They collect them and make new tubes out of them.

The result is the Air Plus tube.

As they are made extra powerful, they are the perfect choice for electric bikes, for example.

At the same time, this extra powerful quality also provides a bit higher puncture protection than usual.
