It's not a theory it's a fact. Talking to the folks at Raleigh USA said this was the reason, but that also many hubs came from Shimano too tight too. This is why we started the experiment described in an earier post. All the hubs we got from Raleigh were too tight.

Sheldon's seen more hubs that me I'm sure and he's right about pitted hubs after years of use. I've also seen many trashed hubs from being too loose also. This is the reason that I said not to try preload unless you know what you're doing. I'm sure if Sheldon tried to use preload he could do it the right way. Maybe my friends and I were lucky or we're brilliant mechanics but I've never had a problem with preload. Of course there's preload and there's PRELOAD.
