Howdy yall! Hoping you guys can help me out! I just got my first Cannondale road bike, but I can't find out anything about it. I'm used to the model of the bike being on the top tube, but it just says Cannondale. The rear triangle just says "cannondale advanced CAAD 3 aluminum design". The front emblem appears to be 2000-2007 according to the Vintage Cannondale website, but there's no sticker serial number and the number on the bottom tube seems to be IRR. It is a Tiagra groupset with a Triple up front. The seat (which could be aftermarket) is also Cannondale Seaco branded... So any ideas? The best guess I have gotten so far is early 2000s R model Trade in frame.
