ItalyRoadBuild sheet

Stamped on the Cavalieri Cambio Corsa, documented head to hub in the Tech Specs Database. The serial identifies the frame, the frame anchored a full build sheet and the registry ties the two together.

Notes

Please do not enter another living person’s name without their permission — describe former owners generally, for example “a French collector”.

Photo links

A clear shot of the stamping helps an editor verify the entry — your own site, Flickr, Google Photos and the like.

You

Credit is public, your email stays private and the serial is masked unless you opt in.

How would you like to be credited?

The only name shown publicly — your real name and email are never published. Leave it as “private collection” if you prefer.

Your email (optional, private)

Only if you would like us to be able to follow up. It is never published.

Show my full serial publicly. Otherwise the registry displays only its first characters — 25••• — and keeps the rest private.

I confirm these details are accurate to the best of my knowledge, any photographs are mine to share, and I have removed or have permission to include any other person named here. I understand Ebykr will publish the maker, model, year, serial number, type, country and condition of this bicycle in the public registry, credited only to the handle I choose. My name, email and IP address stay private. I may ask Ebykr to correct or remove my entry at any time.

Your IP address is recorded privately for moderation. You do not need an account to log a serial.

Reviewed by an editor before it appears — usually within a day.
