What is the significance of these stickers on Shimano Components

This is a FD-6703 with a date code of KF (2012-June), which is pretty close to the KH showing on the round sticker. Are these QC/inspection stickers, or some other meaning? If they are QC stickers with the bottom letters indicating the date they were inspected, what do the top letters mean?

What is the significance of these stickers on Shimano Components

Posted this in the Mechanics Forum but didn't get any replies so trying again here.

This is a FD-6703 with a stamped date code of KF (2012-June), which is pretty close to the KH showing on the round sticker. Are these QC/inspection stickers, or some other meaning? Might make sense, with the final inspection [size=13px]occurring[/size] two months after the [size=13px]production[/size] of the part. If they are QC stickers with the bottom letters indicating the date they were inspected, any idea what the top letters mean?

They show the manufactured date. Shimano has had those in sticker or stamped form for decades.


No idea what the other 2 letters are- I don't remember seeing multiple 2 digit codes.
Maybe thats the country or factory code for where the specific parts were made? WAG.

They could mean anything, possibly as simple as the initials of the inspector.

You might do better on the C&V forum, since this b would be of more interest to those who collect bikes than those who ride or fix them.

Yeah, when do C&V people ever ride or fix their bikes?

Thanks for the reply. I am familiar with the stamped date codes and have used those many times over the years to help determine the model year of a bike. While I remember also seeing the stickers - as you said for decades - I never paid much attention to them. In this case, if the sticker is also a date code, it differs from the date code stamped in the part by two months. That's what made me think it might be a QC/inspection date - close to the production date but not identical. Either way, close enough to not waste any more time.

What? My vintage bikes are supposed to be in working order? I thought vintage was an euphemism for "not in riding condition".

I checked a few Shimano components from around the turn of the Century lying around in my parts pile.... er.... carefully catalogged in my parts bins. They follow this same pattern - second, smaller two-character code indicates the same month/year as the stamped code, or 1-3 months later.
