Yep, Sounds good in theory, & in my daily experiences at work. Guess we'll have to agree to disagree on this one. A Cast Spoke Wheel hub, with studs, & wedges installed, is lighter in weight, than a steel hub, with a steel rim, at least in the applications I've been working with. When I remove a front wheel with the Cast hub, & drum, as a unit, to inspect front shoes, & bearings, it's lighter in weight than removing the front wheel, (with rim), & hub assembly, on a truck with disc wheels.
