Schwalbe Air Plus Tube Nr. 14L-AP – The Tube That Holds Its Breath Longer

Imagine setting off on a long ride and not having to think about your tyre pressure for weeks. That’s the promise of the Schwalbe Air Plus inner tube. Thanks to its exceptionally high proportion of pure butyl rubber, the Air Plus retains air significantly longer than conventional bike tubes — so you pump up less often and ride more. It’s the upgrade your 27.5" wheels deserve.

With approximately 70% thicker walls than standard tubes, the Air Plus also offers above-average puncture resistance against pinch flats and penetrations. And when it does eventually need replacing, it’s 100% recyclable — just like all other Schwalbe tubes.

Frequently Asked Questions

What makes the Schwalbe Air Plus different from a standard tube?

The Air Plus is made with a higher proportion of pure butyl rubber and has walls approximately 70% thicker than a standard tube. This means it retains air much longer — so you need to pump up less frequently — and it offers significantly better resistance to punctures and pinch flats.

What valve type does this tube use?

The Nr. 14L-AP uses an AV (Auto Valve / Schrader valve) with a 40 mm stem length. This is the same type of valve found on car tyres and is compatible with most standard pumps and petrol station air compressors.

What tyre sizes is this tube compatible with?

This tube fits 27.5" (650B) wheels with tyres between 54 and 70 mm wide (ETRTO 54/70-584). It is suitable for a wide range of mountain bike and e-bike tyres in this wheel size.

Is this tube compatible with e-bikes?

Yes — the Air Plus tube is suitable for use in e-bike tyres within the compatible tyre size range (27.5", 54–70mm). Its thicker walls make it a particularly good choice for heavier e-bikes where puncture resistance is important.

Is the Schwalbe Air Plus tube recyclable?

Yes — like all Schwalbe tubes, the Air Plus is 100% recyclable. Schwalbe runs a tube recycling programme, so when your tube reaches the end of its life, it can be returned for recycling rather than going to landfill.

How heavy is this tube?

The Schwalbe Air Plus Nr. 14L-AP weighs 400 grams. The extra weight compared to a standard tube is the trade-off for its superior air retention and puncture resistance.
