Weird Presta valve….what’s this?



What’s this all about? It’s unlike any Presta valve I’ve seen and a Google search didn’t help.

the valve end unscrews completely and is solid, almost like a metal dust cap.

thanks for any advice! Not quite sure how best to pump it up, once the patch has dried!

Barchettaman ,that is a Dunlop valve/stem, not a presta. Do not see many on bikes in the USA. I believe parts of Europe still has a fair amount of use with these. I have no experience with them, cannot even remember actually seeing one, other than pictures.

Ok many thanks. It seems to function like a Schraeder valve with a dust cap that threads internally….super weird. I’ll do a bit of research.


edited to add: it doesn’t seem to be a typical Dunlop valve. The plot thickens.

So it’s not a presta, but a pasta valve?

Looks Like a Dunlop to me, actually have one in the shop. To remove the air, undo the knurled nut and just pull out the core.

It doesn’t have a removable core. It’s like a miniature Schraeder, with the metal end acting like a dust cap but with internal threading.

seems to work ok, so I will just put it in the spares box now it’s been patched. A conventional Presta is now on the bike.

Did a standard presta pump head work on the valve?

it did. In some ways it’s an improved design; there’s no risk of the Presta valve getting bent by the pump head. Like I said, it’s in effect a Schraeder with a Presta outside diameter, really.

Is the inner valve core spring loaded (like a Schraeder) or operated by differential pressure (like a Presta)? I assume it's the latter. I'll probably never see one of these in my life, but in case the subject arises at a cocktail party, I'll be prepared to participate in the conversation.

I’m unable to help; it’s all coiled up in my inner tube box, ready for the next puncture. Dunno.

It's not often we see something this unique - thanks.
I have no suggestions.
I'll remember this for next time somebody asks.

It's not a Dunlop valve. It's a rare valve standard, don't know its name but I've seen a few of them over the years.

So have I, now! It does work pretty well. I’m surprised it’s not more widespread; I was sure all of you chaps were going to be familiar with it.

just for context, my kid bought it when he had a catastrophic tyre/tube failure on his bike packing trip this summer. He went with three friends (all aged 16/17) from Frankfurt to Lake Garda and back to Innsbruck.

The tyre let go as they were on the outskirts of Trentino, fortunately not on a Alpine descent!

That's a Regina valve, mostly found in Italy in applications where a Presta valve would otherwise be used.

^^^^^^ Good to know, but it looks like the functional question (from post # 14) still isn't answered -- is it spring-loaded or activated by pump pressure? Anyone know?..... Bueller?.....

No it's a Schrader-ish valve with a Presta-ish form factor.
