Hi all. I bought a Fausto Coppi K14 Aluminum frame off ebay a few months back and I'm beginning to build it up. It does not have a fork or headset. I had a few questions before I start ordering parts. I measured the head tube and it appears to be rougly 1 1/4 inches. When buying a new fork do i buy 1 1/8th threadless and 1 1/8th headsets?
