<p class="" data-start="330" data-end="651">The Schwalbe No. 21 inner tube is a proven companion for anyone riding 27.5" tires (650B) - whether on the trail, every day or on long routes. With its 40 mm long Sclaverand valve (SV), it fits into slimmer rim bores and is particularly excellent for sport-oriented cycling.</p> <p class="" data-start="653" data-end="1030">A bicycle inner tube may be invisible, but it is essential. That's why a spare inner tube like No. 21 belongs in every set of luggage - just in case. The ETRTO dimension on the tire sidewall shows which tube fits: the first two digits indicate the width, the following the inner diameter. The No. 21 covers a wide range of tire dimensions in the 27.5" range.</p> <p class="" data-start="1032" data-end="1320">Thanks to the uniform material thickness, high airtightness and robust quality, this inner tube provides a solid foundation for every ride - reliable, durable and easy to fit. Whether trail bike or trekking bike: with the Schwalbe No. 21 you are on the safe side.</p>
