Cannondale Criterium! shimano 105 branding. Headset, Bottom Bracket, and seatpost included. This is a small 48cm frame. In nice condition!

(Update as of 5/10/24): added pictures of measurements, 48cm to the top of the seat tube, The top tube is 51cm. I looked through all the historical Cannondale Catalogs and looks to be the 1988 SR500 (at vintagecannondale.com), i previously thought this was the 1987 model but looking at the catalog the blue with white lettering was available in 1988.

Criterium frames are responsive, and quick! I rode one for years and seems like people either love em or don’t. Message me if you have any questions!
