What I've learned so far is that Bottecchia is an Italian full line bicycle manufacturer which was founded by the Carnielli family in the early 20th century. Ottavio Bottecchia was the first Italian to win the Tour de France, 1924 & 25, and was linked to Carnielli. After his untimely death in 1926, the company was reorganized and named in his honor. The company is considered a second tier manufacturer. Their top of the line bike were essentially "club racers". It is rumored that their team bikes, including Lemond's 1989 TdF winner, were built by others. The company is still in business and continues to sponsor pro teams.
