Wheel dishing WAY WAY off
I've had a couple bikes in the recent past that had the craziest problem: The wheels were true in a circular sense but the dishing way way off, like a consistent 10 mm. all the way around. I eventually got them true but it baffled me.
These were old bikes and the only explanation I could think of is they were lying on their sides or tilted up against something for many years.
Any better ideas?

I'm thinking that sometime in the past the freewheel and axle spacers were changed for some reason.

I checked the dish on my trusty Park TS-2 truing stand.
I thought it was so crazy that I flipped the wheel over and voila, the dish was just as bad but reversed .
When I trued it up, the spokes on the "need tighten" sides wern't particularly loose, and those on the "need loosen" wern't particularly tight.
I like the idea of some kind of spacer having been present once.

I had a similar problem on a rear wheel back in the early 90's that came on my Bridgestone MB2. On a normal rear wheel the spokes on the cassette side are shorter than the spokes on the non cassette side. In the case of this wheel they were reversed causing the dish to be way off. I did a rebuild with the same spokes on the proper sides and it dished up perfectly.

My guess goes along with RG. These wheels were used as fixed gear rears.

It's a lot to be off by accident, but I've seen the fixie/SS crowd, in a hurry to be trendy, do far worse to rear wheels. They know just enough to really screw things up but not enough to make sure it's done right. Either that or someone misplaced a spacer.

Did everyone read Bob Barker's reply? To me, that's the only logical answer. A wheel dished improperly by 10mm would likely not even fit between the chain stays properly on most bikes.
