In case you mean if they made different frames for other brands, no. Most of the time it was just a sticker or/and paint. There are a few exceptions, Alan made the Dual and Carbitubo in collabaration with Colnago. There was a prototype for Gios. Guerciotti and Fanini had sometimes their brand engra ved on the fork crown. As you see, I talk for Alan, Vitus is not my knowledge.
