Someone locally is selling a Felt F1 frame for $350 (Dura-Ace BB and FSA fork). I don't know anything about bikes, I have a Marin road bike now and I was thinking I could just figure out how to swap all the parts. Is this a good deal for the frame? It seems like there are different "models" of F1 frame and i don't know exactly which one it is. I attached a picture, hopefully you guys can help me identify the year or exact model and if I should jump on this or not.
That looks like an early 2000ish frame based on the paint and interface from the top tube/down tube to head tube. $350 is a good deal for a frame, but I question what might be wrong with it. Overall, it looks like it is in good shape. You can't compare it to today's F1 frame (which is several thousand dollars). So long as there is no known or visible structural issues, you can't go wrong for that price on carbon. Just be careful with a visual inspection. My guess is the guy upgraded his frame and is just trying to shed the old one.
Your Marin will likely need a few new components. Your crank might not be compatible with that BB and the front derailuer that you have is probably clamp on. You'll need a Braze On for that frame.
