[QUOTE=Ironfish653;19737701]Nope, the H300 on the frame pretty much pins it down.
The biggest indicator would be your tire/wheel size. There's a 'label' visible on the front tire, it should have the size printed on it. You are looking for something like 700x35 or 26x1.75 The first number is the wheel size, the number after the 'X' is the tire width.
Through the 80's and 90's Cannondale's model naming was alpha-numeric: R-X00 for road/race bikes, T-X00 for Touring, M-x00 for Mountain bikes, F-X00 for MTB with the Headshock integrated front end. The higher the number, the higher level bike.
The frame shape originated with the Delta-V, which was their first full suspension MTB. The Headshock was Cannondale's proprietary front suspension, which put the shock inside an oversized head tube, it's light and stiff, but with a shock over 100mm travel, it makes the head tube very tall. (my F-XXXX) has a negative-rise stem like a road racer!) So; tall front end, tall rear end, the 'V' top tube was a way to increase the stand-over clearance, which became something of a visual signature for Cannondale bikes.
Well shuckie darn....I am a little confused. I will need to look it over a lot better when I get off work. I know it has the Hybrid 800 sticker but not a lot more identifying labels....grrr.... I love it I would just like to know more about it, that is all.
