I was just thinking, my Qoroz frame came with no frame number. I never got around to putting one on it.
So, initials, house number and post code, or something less obvious ?
Stamped or engraved ? I’ve got the tools for both, but never tried them on titanium. How hard is it ?

Phone number? In case it ever gets nicked.

i’d use my initials and some numbers for example PW0001.1.4 just cos

5318008

007

pure titanium is relatively soft in it’s annealed condition but work hardens very quickly which can blunt tools if the wrong cutting speed is used or lack of cutting fluid. Alloys will generally be harder. Drawn tubes will be relatively hard if not subsequently heat treated

I agree with bobster though.

Best of all though, 22, the atomic number for titanium

5318008 or 80085

The date it was made, and your birthday..

We use a lazer engraver for all our serial numbers on Ti.

I thought 668 was the fax number of the beast.

My initial thought was the birthday of the bike, but 5318008 wins hands down. 😆

CPL593H, obviously.

Pi…if you can get it to fit?!

You don’t need Pi – you need

Grahams Number

Do you not have a feeling that when this frame breaks, the crack will start at one of the stress concentration points on your DIY serial number? 😉

Didn’t understand the 5318008 joke for a while, then I remembered my schooldays 😉

Its a joke for people who turn their bike upside down to fix a puncture 🙂
