I purchased this frame at the end of last year in northern Italy. I initially identified it as a 93-94 M2 but the paint scheme is special. The previous owner told me it was the official bike of an MTB team from Biella, Team Zola. The team was sponsored by specialized and Zola itself was one of the first specialized dealers in Italy from 1988. The paintwork and decals are the S-works division one but the production number (90T00074) suggests this is one of the very first frames produced in 1990.
I've been trying to better identify the frame but right now I'm stuck with the investigation. I hope someone has some info about it.
For now, the only hypothesis I can make is that the frame was Unsold or archived (I've seen this practice with early production numbers in many bicycle manufacturers) and later issued for this small team in Italy. Or maybe it was aesthetically renewed for the team, this hypothesis does not convince me because I don't see the point in changing not just the decals but also the colour with a complex chromed finish.
