I’m a little late to the party but that article is mostly useless. It really doesn’t address the problem. His advice of “My advice to female under 5’ 4” would be to buy a frame in the smallest size possible,” is right out of the Captain Obvious Big Book of Obviousness.

First, 5’4” tall isn’t “small” for a woman. It’s average…as in the middle of the height range. Half of all women are smaller than that. I wonder what men would say if bicycle manufacturers said we can’t build bikes for men shorter than 5’9”.

A far better article on the problem with solutions is Georgena Terry’s post on frame design. At least she suggests solutions.
