It was mentioned in a recent thread about the Suzue Jr. hub that the cones should be adjusted with just a little play, which would go away once the wheel was bolted back onto the bike. This is commonly done with QR axles because when the QR is properly tightened, the hollow axle flexes enough affect the cone tightness.
But. Would a solid axle flex? I'd think there would be too much material in a solid axle for it to compress once bolted down. However, it would suck to find out that I've been inadvertantly over-tightening my cones and increasing wear on my hubs. Opinions?
