My '89 Centurion Ironman (Expert) frame measures 57cm (C2C) on the seat tube, 59cm (C2C) on the top tube.
My '92 Specialized Crossroads has a 53cm (C2C) seat tube, 60cm (C2C) top tube. It takes wide 700c/28"/29" tires.
I've got a '94 Diamondback Parkway frame around here somehwere with a 56cm (C2C) seat tube and a 61cm (C2C) top tube.
My '83 Bianchi Grizzly frame has a 57cm (C2C) seat tube, and a 60cm (C2C) top tube. Unfortunately it's designed for 26" (ISO 559) wheels.
I seem to recall the Giant Boulevard hybrid has a longer top tube as well.
