My uncle gave me this Cannondale yesterday. It doesn't seem to have a factory model decal. It's a 14 speed with very reliable and smooth Suntour components. The frame is fatter than most road bikes I've ever seen but its very light. It also has San Mistral M13 630 aluminum wheels with quick release hubs. Frame is small but fits me just right. Can someone give me any info? I could not find any info online. The serial number on the bottom of the rear dropout reads: 21040987137 and the down tube says 58925.
I also need help on how to air up the tires. It has a valve stem that has a screwable piece.
