As @

Does it matter if the rim is shallower if it's faster? That just means less weight, and less vulnerability to cross winds, right?
But that design choice [hookless]
has allowed this wheel to become more efficient overall. It has a more bulbous rim profile that allows the tire to sit wider, meaning less tire deflection, a shorter contact patch and reduced rolling resistance. Energy lost to vibrations in the road has also decreased thanks to higher volume tires running at lower pressures.
