Talk:Dunlop valve

Needs better explanation
This article needs a cross-section diagram of a Dunlop valve and a paragraph that explains the theory of operation. &mdash; QuicksilverT @ 22:35, 1 May 2013 (UTC)

Dimensions
It would be nice if the article gave the dimensions of the valve, including the diameter of the large stem. (Ie, will a Schrader valve fit the same hole?).drh (talk) 20:31, 2 March 2014 (UTC)


 * Yes. I've slightly cheekily added a weak reference to that effect - shades of OR, since really I just happen to know it's true - there are only two rim drillings, Presta and Schrader/Woods. Pinkbeast (talk) 13:06, 3 March 2014 (UTC)

Dunlop not compatible with Presta valve adapters
I'm not sure where the editor thought that Dunlop was compatible with Presta valve adapters. That's not what the link to Sheldon Garon's site says and I know from personal experience (yeah yeah, unsuitable for making a counter claim but it's what lead me to follow the link which doesn't say what the claimant says it does) that it doesn't.

Claim of compatibility is deleted until proof is shown. — Preceding unsigned comment added by Nasukaren (talk • contribs) 04:04, 6 April 2014 (UTC)


 * The link says "You can pump them up with a Presta pump" (and you can, I've done it lots of times). Seems clear enough to me. Pinkbeast (talk) 15:03, 7 April 2014 (UTC)

The tip portion is close to Presta proportions but is short and many pumps don't have enough "grab" to create a proper seal. Source: my experience. Sure, I'm not Sheldon but I've lived in Japan and sworn at enough Woods to know that the length is a major issue. Nasukaren (talk) 01:42, 22 July 2014 (UTC)


 * Feel free to produce a citation from a reliable source to that effect. Pinkbeast (talk) 11:18, 22 July 2014 (UTC)


 * Presta pumps definitely do *not* fit on a Woods valve. I had to buy an adapter. Richard W.M. Jones (talk) 09:57, 19 October 2015 (UTC)


 * So _produce a cite_. I mean, I think it works, you think it doesn't, maybe it works sometimes... but citations are how we do things and if the late great Sheldon says it works... Pinkbeast (talk) 12:19, 19 October 2015 (UTC)

My experience is that Presta adaptors work sort of / poorly. The diameter of the valve is the same or almost the same, but the Dunlop/Woods valve is much shorter and (as cited above) you don't get enough of the valve 'swallowed' to get an effective seal. So you end up cursing and pumping a lot to get very little air injected. — Preceding unsigned comment added by 209.82.26.141 (talk) 14:53, 26 April 2017 (UTC)

Name
I'm not a bike nut but I've never, ever heard this valve referred to as a 'Dunlop' or 'English' valve. If this is just American usage, the article should say so. --Ef80 (talk) 18:53, 3 August 2014 (UTC)


 * One of the cites in the article is to a Japanese site referring to it as an "English" valve, so I don't think it's just Yanks. Pinkbeast (talk) 11:58, 4 August 2014 (UTC)


 * The Japanese do generally use American English though. --Ef80 (talk) 13:52, 22 August 2014 (UTC)
