Which bike part do you think is the one that can be easily interchanged between bicycles and cars?
That’s simple! – the Schrader valve caps…
Apart from the occasional Woods/Dunlop (old roadsters?) and Presta (racers?) type valves, most bike tyre valves would be of the Schrader type. The obvious advantage of these is that you can use automobile tyre pumps, as well as fit automobile valve caps to them.
I do try to keep nice ones on my “classic” bikes and I have a couple of jars that I keep them in, ready to swap them over to the next project. The caps help to keep grit out of the tyre valves and may also help to slow a leaking valve in some cases, if they have an airtight seal on it.
I wonder if anyone out there has a major collection of these – I have a few in my stash that I find vaguely interesting, and of course there are modern gimmicky ones that you can buy from auto shops too, like coloured anodised dice, bullets and 8-balls for example (I think that little skulls would be a good theme, e.g. for fixed gear or BMX). I did see some flashing blue LED light versions for bikes advertised recently too…
Though appearing much the same here, when I looked closer, the cheap plastic ones below have a wide variety of brand markings on the tops – oddly collectable maybe, but they just don’t do it for me …
I am more interested in the old metal ones, and though I haven’t gone out of my way to gather them, I think that if I were a collector of such things then at least they wouldn’t be taking up a lot of space, unless each one was attached to a classic bike, that is!
Of course, this smallness of scale also means that only the most ardent and obsessive of bicycle spotters will admire your stunning array of vintage valve caps – most will be too busy checking out the rest of your lovely restored classic to even notice … teehee.
When I was a kid, I can remember fixing punctures with vulcanising patches that worked by clamping a disc to the tube, scratching the back and lighting it (gunpowder in paper?) and then waiting for it to cool to peel off.
I think there are some pieces of these below, along with an old dunlop patch & glue kit and valve extractor tools :
Total trivia, huh?
