Serotta Atlanta with matching steel fork, 1" threaded. ST 61 c-c, 63 c-t, 73 degrees; TT 61cm c-c; HT 20.7cm, 73 degrees, WB 104.5cm; C-stay 42cm; BB drop 7cm; Stack 62cm; Reach 44cm. This frame is made of Colorado Concept Tubing and is the liveliest and quickest steel frame I've ever ridden. It's just too big for me (I'd prefer a 60cm with a 58cm TT). The paint was mistreated by the previous owner, which is unfortunate because the pearl white with red decals is really beautiful. I had the frame built up with 11-speed Record and it was a thrill to ride. Rear spacing is 130mm, Seat post is 27.2. All threads are excellent. No dents. Headset isn't included. Serial number indicates a 62cm per Serotta sizing.
