Cannondaleriders

Is there only 1 style of subframe for the quads or were there changes sometime.I am looking at another stock subframe and wanted to know if I should look for a specific year?

Where is that encyclopedia?

As far as I know, they are all the same. I have not noticed any differences in any years. How much you paying?? I got a couple laying around here. Got the "R" kit about 1/2 done, should be done by the group ride.
