The total weight of a wheel set is not the best way to judge how
well they'll work in your application.

The majority of the rotating weight is in the rim....far outboard
from the center of the rotating mass. So it makes more sense
(to me, anyway) to look at the weight of the rim (and tire) as
the factor in deciding how much oomph it takes to accelerate.

Does that make sense at all ? This is why a lot of the deep V
stuff is not always a good choice if you want gofast wheels.

But for what I do here, even a rim like the Alex adventurer
seems to work out pretty well for me. Certainly they are
very strong and resistant to road hazard.
