Time to pick a fight -- :-)
Dale's request for a Weinman Concave rim for a friend got me to rummage through the pile (found one, attached to a first generation DuraAce 120 mm rear hub!) and look at the darned thing again. Somehow, I just never "got it" with these rims. For those who don't remember, they were pretty high class, with very tall sidewalls for brake surfaces, and a concave appearance between the walls.
Disadvantages: Unless you spoked them weird, with left spokes reaching the right spoke holes, and vice versa, the spokes emerged from the holes at a very awkward angle. Big sidewalls = more weight.
Advantages: could be real clumsy setting up brakes, and tall sidewall gave more radial stiffness.
What am I missing?
