You can’t even see Schwalbe’s No. 19 F inner tube on the bike, and yet every bike needs (at least) two of them: bicycle inner tubes.

The inner tube has to be the right fit! For most tires, you can find the correct size on the sidewall. The ETRTO measurement indicates the tire width with the first two digits and the tire’s inner diameter in mm with the following digits. The “No. 19 F” covers numerous widths for 29” tires. The “No. 19 F” features a 40 mm long Sclaverand SV valve.

• Bidex code: 204050
