Schwalbe Air Plus Tube Nr. 19-AP – Longer Air Retention for 28"/29" Wheels, Presta Valve

Whether you’re rolling through the city on a 28" trekking bike or tackling trails on a 29er, the Schwalbe Air Plus Nr. 19-AP is the inner tube that quietly outperforms everything standard. Made with a high proportion of pure butyl rubber and walls approximately 70% thicker than a conventional tube, it holds air significantly longer and resists punctures and pinch flats with ease. Fit it, inflate it, and get on with the ride.

This version uses a SV (Sclavrand / Presta) valve with a 40 mm stem — ideal for rims with a narrow valve hole. It fits tyres from 40 to 62 mm wide (ETRTO 40/62-622), covering a wide range of 28" and 29" applications from trekking to trail riding. And like all Schwalbe tubes, it is 100% recyclable.

Frequently Asked Questions

What is the difference between the Nr. 19-AP SV and the Nr. 19-AP AV?

Both tubes are Schwalbe Air Plus for 28"/29" wheels (ETRTO 40/62-622) with the same tyre width range and Air Plus benefits. The only difference is the valve type: the Nr. 19-AP SV uses a Presta (SV) valve, while the Nr. 19-AP AV uses a Schrader (AV) valve. Choose based on your rim’s valve hole size — Presta valves require a narrower hole.

Is this tube compatible with both 28" and 29" wheels?

Yes — 28" and 29" wheels share the same ETRTO rim diameter of 622 mm. The difference is in tyre width and marketing convention: 28" is typically used for trekking and city bikes, while 29" refers to mountain bike wheels. This tube fits both, as long as your tyre width falls between 40 and 62 mm.

What valve type does this tube use?

The Nr. 19-AP SV uses a SV (Sclavrand / Presta) valve with a 40 mm stem. Presta valves are narrower than Schrader valves and require a Presta-compatible pump head. They are standard on most road, trekking, and mountain bike rims with a smaller valve hole.

What makes the Air Plus better than 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 results in significantly better air retention (you pump up less often) and above-average resistance to punctures and pinch flats.

Is this tube compatible with e-bikes?

Yes — the Air Plus tube is suitable for use in e-bike tyres within the compatible size range (28"/29", 40–62mm). 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 Nr. 19-AP 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.
