Eh? 40% of the cost of a hub is the QR axle/skewer? Really? I suppose if you have a sufficiently cheap hub but then 40% of a cheap hub is still cheap.
When you get into a more expensive hub, the pass-through cost of the QR is small in comparison with the total package.
And there are fine solid axle hubs out there, they just tend to be old or for single speed use.
