Nobody. But people love biking... some a few too much. People at some point start paying, like, $10 per gram reduction. And of course it's exponential; like trying to accelerate to the speed of light, the closer you get to the goal (zero weight) the more you pay per unit improvement.
But. Let's be real here. Just like most products like this, there are two points to note. One, this is a halo product, not intended to be bought except by people with more money than sense or so much money they don't give a shit; this is a product that advertises their "under $3300" wheels. Please note that you are giving them free advertising, which is exactly what they want. Two, people invent fantastic things, charge top dollar, and reinvest the earnings until the fantastic thing becomes commodified and available on increasingly lower-end models until one day it's the bare minimum. (Most new cars today are faster than the fastest race cars of a couple generations ago, and can sustain those speeds for weeks at a time before something breaks, at a tiny fraction of the inflation-adjusted cost.)
