Ok, I started this thread because the Tommasini/Gorilla frameset looked slightly interesting to me. After reading the post from Thomas/Mozzy explaining the situation, I choose to believe him.

I really don't see a reason why anyone would go through all the hassle to counterfeit a steel frame and claim it's made by Tommasini. Wouldn't it make hundred times more sense to fake something fancier and more expensive, like a Cinelli Super Corsa Pista or something?
