Circa 1975 Colnago Super 56cm frame ctc seat tube and head tube is about 55.5 ctc - This frame is straight, strong, true, no shakes, no shimmies - thinnest seat stays I have ever seen on a frame - I rode this bike for about 5 years but finally bought a 57cm as this was just a little too small - I am 5' 10.5" and weigh 205 lbs - even with my weight this frame never flexed - Had my LBS install NOS headset and bottom bracket circa 2003. Has usual paint nicks and scrapes but repaint was done by CycleArt so all decals and lettering are done very nicely. Will ship via US ground to CONUS only. Shipping and handling via standard bicycle box - $75. This a very technically superb vintage frame that someone needs to appreciate and enjoy.
