The gritty feeling caused by excessively tight bearings would be easily felt with the wheel off the bike and the axle turned by hand, but the bearings would have to be *super* tight for this to be felt while riding. I wonder if the QR alone is capable of this much compression.
And, not to pick the old scab, the axle
compresses when the QR is tightened. This is not unreasonable, because steel is an elastic material. If the axle actually did bend, the metal on the outside of the bend would be stretched, and the metal on the inside would be compressed. This could actually be measured.
