Ok I bought a replacement frame on the cheap and wanted to get some feedback. Its a compact made from columbus airplane tubing with a ritchey wcs full carbon fork, fsa headset. It has carbon chain and seatstays.

I bought it for $220. My hesitation came from the fact that its a K2 frame. Its an 04 model which is before Iron Horse bought them out and is a much nicer frame than what is sold today with under the K2 label. Welds are smooth paint is super nice.

Anybody have any experience with these frames or the materials? I haven't been able to find out much about columbus airplane other than its commonly used by some of the big name italian builders.
