Campy Record QR Skewers- "Locked"
My circa 1984 Campagnolo Record hub skewers have "LOCKED" AND "UNLOCKED" on the levers. I have a crazy question: was this just an American-market thing? Are there the same era levers that don't have that on them (or have the markings in other languages)? I know it's really a bit of trivia, but I was curious. Thanks!

Kidding aside, this does looks like a "lawyer" thing to me, which would indeed indicate an American market precautionary measure.

It is rare that a manufacturer would make a country specific language marking on a part, especially on one that requires tooling, like the QR. It is just too hard to track inventory to get the right part to the right country.
When Campy did change things for the US market, like the curved QR levers, rounded brake QRs, covers for RD adjustment screws that came from US CPSC rules in the 70’s they did it globally. Bet when LOCKED was added to the QR, it happened everywhere.

Thanks for all of the replies! I thought it might be universal, but wasn't sure.

The "Locked" and "Unlocked" markings were a CPSC compliance change. Prior to about 1976, the QR levers were straight and not marked "Locked" or "Unlocked."

I'm absolutely certain it was a "lawyer thing", aimed squarely at those with litigation-happy frames of mind here in the US of A

I have a number of quick-release skewers that have CLOSE and Open on them.

IIRC, my Mavic hubs have skewers that says "OPEN" and "CLOSED".......

I am not convinced that OPEN/CLOSED or LOCK/UNLOCK would be enough to cause a person, who doesn't know about QR of any kind, to stop and think about the mechanics of what it is intended to indicate!

Test the bike with the chain in the large chainring. Otherwise all bikes would still have chainguards.

If your name is Oscar C Krumplage, Charles K Effington, or something similar, you can have your initials engraved on it with a little file work.

CPSC - Protecting US From Ourselves!

That was THE FIRST thing that I did when I got home with a used and abused Iron Man that I bought without wheels...
I thought that the old style Campy flat brake QRs were the most elegant part of the gruppo! They just felt right!
You could loose an eye on that QR!
We were importing Andre Bertin bikes back then. We ignored the CPSC ruling in 1976 because most component makers hadn't started producing approved parts yet and the rules were still being debated.
In 1977 we had Bertin start stamping "traceable" serial numbers into the frames and using CPSC approved components as they became available. The whole serial number thing was a joke because few if any European bike makers kept records on their products (Raleigh, Peugeot and a few others all of which are long gone with all of the traceable records).
Unfortunately the CPSC rules did little to protect naive bicycle buyers from the unsafe at any speed department store kid killer bikes that they were supposed to keep off the market!
Bicycles were still considered to be KIDS TOYS by most people in the US.
One thing that it did do was discourage some European brands from exporting bikes to the US. YOU WANT US TO DO WHAT!

Routine was the exercise when a bike with a front quick release came in for service, we would test the quick release.
We would test the rear too in the stand but the front was the most common to be customer removed.
About 25% of the time the skewer was just wound tight.
We would show the person who dropped off the bike the correct procedure, then have them test "feel" the engagement.
Asked that the person who most often rode the bike to come with upon pick up.
Then show that person too.
Many an "AH Hah" moment.
Most of these bikes had manuals upon sale, rarely did they get read.
The second most common error was not understanding the brake QR to open up the caliper for the tire to pass.
We would always show buyers of a bike how to operate. People forget.

I am not convinced that OPEN/CLOSED or LOCK/UNLOCK would be enough to cause a person, who doesn't know about QR of any kind, to stop and think about the mechanics of what it is intended to indicate!
