But after emailing Mr. Zullo himself, he replied that the frame was intended for riders who weigh no more than 143 lbs. Not 140, but 143 (so specific!) That could have been catastrophic for me, as I weigh 188-190. So, even as to this Alan frame, I probably have to give it a pass and get into a much newer product.
That's almost exactly 65 kg, which makes the chosen weight limit seem less arbitrary.
I once saw a Columbus catalog that specified a weight limit for SL steel tubing of 180 lbs and lower limits for their lighter tube sets. There might have been a number of other European manufacturers that had weight limits for their products, but it's likely that very few of us in the U.S. knew about them.
