Vintage Cannondale what I can only presume to be an f-3000 frame I have done some research and couldn't find exactly what I was looking for when looking for this frame My best estimation is that it is an f 3000 overall it's in decent condition bottom bracket has some play shock holds air and functions like it should It is measured 18 in center to top of top tube if you have any more information on this frame please let me know considering I am not positive of what it is. I looked through the Cannondale catalogs and it seems harder to find the right one especially without decals it makes it a lot harder. Thanks for looking please let me know if you have any questions before purchasing Thank you thanks for looking please let me know if you have any questions before purchasing Thank you
