google turns up several references to 'cellini' bicycles, as far back as the 70s and as current as a full-carbon monocoque tri bike. no luck finding a mfg website in my 3min of looking...
Lots of people subcontracted people like Merlin and Litespeed to build flagship models for them. Also lots of shop-sponsored teams also rebadged Ti bikes in their brand.
I bought a Litespeed badged as a Morati - the shop had done it as a promo special and when I checked the number with Litespeed it was confirmed as one of theirs.
Cheers.... hopefully I'm edging closer to figuring it out. from what I can make out they seem to have some sort of history in Triathlon.
Does the fact no one knows that much about it point to the fact it's rare and unique or a worthless pile of dung... who knows, but if it really is titanium it's gotta be worth a look right?
