Frequently Asked Questions (FAQ)

What tyre sizes is the Schwalbe Tube No. 19 compatible with?

The No. 19 covers a broad range: ETRTO 40/62-584/635, which translates to 27.5 x 1.50–2.40", 28 x 1.50–2.40", and 29 x 1.50–2.40". Check the sidewall of your tyre for the ETRTO code — if the first number is between 40 and 62, and the second number is 584, 622, or 635, this tube fits.

What valve type does this tube use?

The No. 19 uses a Schrader valve (AV – Auto Valve) with a 40 mm stem. Schrader valves are the same type found on car tyres and are compatible with any standard pump, including petrol station air compressors. No adapter needed.

Is this tube suitable for MTB use?

Yes. The No. 19 is specifically designed for the wide tyre widths (40–62 mm) common on MTB, gravel, and trekking bikes. Its robust butyl construction handles the stresses of off-road riding and varied terrain well.

How do I know if this tube fits my bike?

Check the sidewall of your tyre for two numbers, e.g. 50-584 or 57-622. The first number is the tyre width in mm (must be between 40–62), and the second is the rim diameter (must be 584, 622, or 635). If both match, the No. 19 is your tube.

What is the difference between a Schrader (AV) and Presta (SV) valve?

A Schrader valve is wider, has a spring-loaded pin, and is compatible with all standard pumps including car pumps. A Presta valve is narrower, lighter, and requires a Presta-specific pump head. Check your rim's valve hole size before purchasing — Schrader holes are wider (~8 mm) and cannot be used with Presta tubes without an adapter.

Why is butyl rubber the preferred material for inner tubes?

Butyl rubber offers excellent air retention, meaning you'll need to top up pressure far less often than with latex tubes. It's also more durable, more puncture-resistant, and more affordable. For everyday riding, commuting, and touring, butyl is the industry standard.

How do I install the Schwalbe Tube No. 19?

1. Remove the wheel and fully deflate the tyre. 2. Use tyre levers to unseat one bead of the tyre from the rim. 3. Remove the old tube. 4. Lightly inflate the new tube to give it shape. 5. Insert the Schrader valve through the rim hole and tuck the tube evenly inside the tyre. 6. Reseat the tyre bead by hand — avoid metal levers on the final bead to prevent pinching. 7. Inflate to the pressure recommended on your tyre sidewall.

What inflation pressure should I use?

Always follow the min/max pressure printed on your tyre sidewall, not the tube. For wide MTB and trekking tyres (40–62 mm), typical pressures range from 2.0–4.5 bar (30–65 PSI). Lower pressures improve grip and comfort on rough terrain; higher pressures reduce rolling resistance on smooth surfaces.

Is this tube sold individually or in a pack?

This listing is for one (1) tube. Trade cartons contain 25 units (VE: 25).

What is the difference between Schwalbe Tube No. 19 and No. 19 AP (Air Plus)?

The standard No. 19 uses conventional butyl rubber. The Air Plus (AP) version features a thicker butyl wall for enhanced puncture resistance and even longer air retention — ideal for loaded touring, bikepacking, or urban riders who want maximum reliability between maintenance checks.
