Running wide 27.5" or 27.5+ tyres? The Schwalbe Air Plus Nr. 14L-AP is the tube that keeps up with your ambitions. Engineered with a high proportion of pure butyl rubber and walls approximately 70% thicker than a standard tube, it holds air significantly longer and shrugs off punctures and pinch flats with ease. Fit it once, pump it up, and forget about it — that’s the Air Plus promise.

This version uses a SV (Sclavrand / Presta) valve with a 40 mm stem and is designed for wide tyres from 54 to 70 mm (ETRTO 54/70-584), covering both standard 27.5" and the chunkier 27.5+ format. Like all Schwalbe tubes, it is 100% recyclable.

Frequently Asked Questions

What is the difference between the Nr. 14L-AP SV and the Nr. 14-AP SV?

Both are Schwalbe Air Plus tubes for 27.5" wheels with a Presta (SV) valve, but they cover different tyre widths. The Nr. 14-AP SV fits narrower tyres (40–62 mm, ETRTO 40/62-584). The Nr. 14L-AP SV fits wider tyres (54–70 mm, ETRTO 54/70-584) and is also suitable for 27.5+ format. Choose based on your tyre’s width.

What is 27.5+ and is this tube compatible?

27.5+ (also called 650B+) refers to 27.5" wheels fitted with extra-wide tyres, typically 2.8" (70 mm) or wider. This tube (ETRTO 54/70-584) covers tyres up to 70 mm wide, making it compatible with most 27.5+ setups. Always check your specific tyre’s ETRTO width before ordering.

What valve type does this tube use?

The Nr. 14L-AP uses an 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 mountain bike and trail rims.

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 (27.5" / 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 Nr. 14L-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.
