Clever Bugger....
 
I bought an old steel framed Fuji a few years ago, stripped it down, and threw the pedals in a bin. I pulled them out today to see if they're worth keeping, and noticed this (see photo). The previous owner discovered the threading on a Presta valve was the same as the pedal screw, and put a Shrader/Presta adapter there to have it available if he needed it. I was a bike messenger for over five years, before clipless pedals, and I can't believe I didn't think of this.

In your opinion, which forum would have been better to show a C&V pedal hack than C&V?

This sounds like something my sister in law would say...no matter which route I take to a destination, she'll tell me about another one I could have taken.

There are probably quite a few screws on bikes onto which that adapter would fit.

I leave mine on one of the valves, 50% of the time it could not be closer to where I need it.

Clever that. Thanks for posting!

A PV adapter carried on the pedal was a pretty common practice at one time. A time when you topped off your tires at gas station air pumps ( for free! ) and refilled your water bottle ( always singular) from the radiator filling hose while you were there. Of course you did have to listen to the gas station attendant ( unless you live in Oregon or NJ, you might need to look up that term) tell you that your tires would explode if you put in more than 50 psi. But that was less of a hassle than trying to fill tubulars with a Silica frame pump.

How much trolling does it actually take? Is it not against forum rules? Enough, please.

There's an ignore list in the user control panel. ;)

They also fit on the back of the clamp bolt of most C+V Campy Record, Nouvo and Super FD's. ;)

Same here. I put mine in my patch kit.

Funny that I have found several that looked just like this, a bit crusty, rusty, lost in time, forlorn and forgotten like many of the bikes we covet. :twitchy:

That's a weird place for your ignore list. :)

mechanicmatt 09-11-21 05:33 PM

Um does no one else...
 
...just flip it upside down and use it as a stem cap? I've been carrying it this way since I was a kid.

That adaptor-on-the-pedal-screw trick takes me back.

I notice that all of the adapters pictured so far are the short version. In the mid-1960s, when I started riding racing bikes, the common Presta adapter was about a cm taller and would have been the standard version in Europe. But some, maybe most, ignorant American would-be racers (I include my 13-year-old self and the guys I rode with in the local bike club in that category) assumed that Presta valves worked like Schraeder valves and so insisted on short adapters where you could see the top of the valve stem. So the longer adapters eventually disappeared from the bike stores.

You can't use a normal pressure gauge with the long adapters - that's why the short ones became popular. It's not about seeing the top of the valve stem, it's about whether the center of the pressure gauge reaches it to press it down.

I did that way back but people keep quoting him and I still see his pearls of wisdom.
And I paraphrase, 'Everytime onyerleft posts something, an angel dies'
Trolling for the Lord indeed, just sayin'

His tag reads: "Pedaling for the Lord!"; methinks it would be more accurate if it read: "Trolling 'cause I'm Bored". :rolleyes:

[MENTION=168558]Drillium Dude[/MENTION], agreed.


On these valve adapters, I have a few, but only use one all the time here. Years back I picked up a pack from somewhere local, and when I went to use one of those new ones, it would not keep a seal. When I compared it to my old one I found that the little O ring in the Presta side was much thinner. Haven't gotten around to replacing them.
