Can anyone enlighten me as to the location of my serial number? I see two candidates: on the outside of my BB shell is a painted-on (under the clearcoat) number, BI-0038. Additionally, on the bottom of my downtube is a small riveted-on metal tag with a much longer series of letters and numbers on it. Which is which? And what's the one that ain't the serial number? Anybody?

I'm an Orbea dealer in Italy. Frame serial number is on a small riveted-on metal tag.
