Two beautiful red Pinarello frames. Pinarello Gavia built with Columbus TSX tubing and Pinarello Montello built with Columbus SLX tubing. The first owner of Pinarello Montello was known Slovenian cyclist Jure Pavlič.
They are looking similar, but the difference is obvious. The red paint scheme is little different, too. Gavia is darker red than Montello. If you look better you will see the difference between them.
Here are some differences between the frames.
