href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>) is a type of pneumatic <a href="/wiki/Valve_stem" title="Valve stem">valve stem</a> in use—mostly on inner tubes of bicycles—in many countries, including Japan,<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Korea, India, Pakistan, Sri Lanka, most European countries, and a number of <a href="/wiki/Developing_country" title="Developing country">developing countries</a>. The Dunlop valve has a wider base than a <a href="/wiki/Presta_valve" title="Presta valve">Presta valve</a>, similar enough in size to a <a href="/wiki/Schrader_valve" title="Schrader valve">Schrader valve</a> to use identically drilled valve holes in rims,<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> but it can be inflated with a Presta valve adapter.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> The inner mechanism of the valve can be replaced easily, without the need for special tools. </p><p>The Dunlop valve originally used a tight rubber sleeve (see illustration of "original plug") which had to be forced open by air pressure while pumping (not only were these difficult to inflate, but the rubber would perish over time, allowing leakage and eventually, complete failure), but modern Dunlop valves use a different plug (core) using either an internal ball bearing or a spring-loaded rubber plug that is unseated by pumping, making the valve as easy to pump as a Presta valve. </p><p>The inventor was C. H. Woods. It superseded <a href="/wiki/John_Boyd_Dunlop" title="John Boyd Dunlop">Dunlop's</a> original valve for pneumatic tyres.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span
