If aero helps on 10-15mph hill climbs,
I sure can't notice the difference... at least with the rim depths we're talking about here. The Neuvations certainly don't seem to climb any faster or more efficient than the box-section rims they replaced. They
do seem a bit better on the flats when trying to maintain a faster pace, but even there the difference doesn't seem huge.
