10.7 commuting miles today with no issues , even managed a couple of cycle path scalps .
Even had time to go and find a gate .

Ah, but did you go full period and seek out tubes with Wood's valves - ?Tyre and tube now replaced

Sounds like a rough neighbourhoodJust gone in the garage to do some work on my Carlton and guess what the rear tyre is flat again , so had to sort that out instead
The cycle path's i use are strewn with glass and hedge trimmings so hardly surprising
They're fairly easy to find on this side of the fens, which is good as they're brilliant.Wise; there's a very good reason why it's difficult to get Wood's valves now - !

Half odds don't even stock any 26x1⅜ here, despite Bobbin and others still making new bikes that use them. Even other car spares chains like Wilco Fast Fit and the now- closed Motor World stocked them.Must admit my local bike shop stocks them as well , but i bet Halfords and many other bike shops wouldn't know what they are
As I recall, the last time I used Wood's valves, they were 'one piece' as oppose to the original types where you had to periodically replace the wee length of rubber covering the inner valve hole.They're fairly easy to find on this side of the fens, which is good as they're brilliant.
Yes, most Woods valves use a captive ball bearing now, with air pressure holding it tight against its cups until air pressure gets high enough to open it, like this diagram:As I recall, the last time I used Wood's valves, they were 'one piece' as oppose to the original types where you had to periodically replace the wee length of rubber covering the inner valve hole.

That flange on the neck pushes against a rubber washer inside the top of the collar which is normally screwed down tight unless you want to deflate it:

I think all 'Woods' valves had the 'ball-bearing' and rubber ring and the tube was like a 2nd line of defence/bodge for when the rubber 'O' ring failed, I certainly remember 'Woods' valves without the tube (although it may have 'shot off' and been inside the inner tube)They original ones fitted had the rubber tail but that had long persihsed
Here's a diagram of how the classic rubber tube design worked, from the same source:I think all 'Woods' valves had the 'ball-bearing' and rubber ring and the tube was like a 2nd line of defence/bodge for when the rubber 'O' ring failed, I certainly remember 'Woods' valves without the tube (although it may have 'shot off' and been inside the inner tube)
