Considering that the loops disappeared about the time of the CPSC "safety" changes, it seems a lot more likely that the loops were removed because the CPSC considered them a hazard to other riders. This is from the group that turned NR brake QRs into coke spoons to make them safer! I find it hard to imagine that Tullio cared enough about wide American feet and the resulting strap rub marks on cranks, to change a perfectly good part for that reason. The only OTHER reason I can think of would be that the black anodized alloy pedals had no loops, and perhaps a worn stamping die was replaced with a new one that cosmetically matched the "loopless" alloy pedals. This is all somewhat conjecture, and if anyone knows or sure speak up, but the change is so close to the CPSC changes, that I lean to that being the answer, until presented with more of the story.
