Are 130 BCD chainsets stiffer than 110 BCD? I would expect the crank spider not to sacrifice much stiffness in expanding from 110 to 130, but the chainrings seem flimsy in comparison.

Do I buy extra stiffness by using a standard chainset instead of a compact?
There's little difference noticeable but the chainrings will make a big difference as some cheap ones will flex a surprising amount
