Back in the 80s, it was standard practice to design road bikes with no toe overlap. DeRosa and most others did it by extending the wheel base, or making the top tube a centimeter longer, at a time when riders were getting used to being a bit more stretched out on the bikes, per Cyril Guimard, Hinault's and LeMond's coach.
It's always a relief riding a DeRosa. I can track stand on it pedaling back and forth and turning the front wheel as much as I want. I never hit the front wheel jerking around road debris, and can pedal through right turns on sidewalks for example. It has a long top tube, but still steers quickly with a steep 74.5 degree head tube angle, which places the front wheel back compared to the more favorable 73 or 72 degree angles favored today.
Except for very small frames, I still can't see why bikes have to have toe clip overlap to handle properly. My commuter has it, and it bugs me frequently in tight corners and waiting for cross traffic without unclipping. A friend who owns several Colnagos, a DeRosa and some other high end mounts, considered overlap a problem after riding this bike. He wouldn't own one. I'm stuck with mine. If it had an inch longer wheelbase, or an inch longer top tube, and the front wheel were a little further out in front, it would handle just fine.
