Dale Saso recently built a nice KOF frame for me with 531 tubing (from Bicycle Classics), Nervex Pro lugs, Georg Fischer fork crown, Cinelli SCM bb shell, and other classic bits. [I have to thank fellow CR member Dave Patrick for the lugs and fork crown as well as the CR list/Dale for providing the forum for obtaining these parts.] I built the bike up with mostly modern components (though I did use a classic Nuovo Record headset and pre-Columbus Cinelli handlebars and stem). The bike rides amazingly well. It feels like a much lighter bike, and is very responsive yet steady through corners.

[You'll have to excuse the fact that I am a lousy photographer.]
Dale is located in San Jose, CA. He has been building frames since ~1972, and therefore has a good appreciation of the desired qualities of a KOF frame. If you wish to contact him, he can be reached at: dsaso@aol.com, (408) 258-5574, http://sasobike.com
