Now dont come at my talkin about Surly and Iro or Soma...those arent track bikes. The Concept is a ****in battle tank when it comes to track bikes.

Framebuilders forum might be of better help. I can make something up about the moment of interia and hardness or rust prevention or something, but it will probably be wrong.

I'll make somehing up and I'm probably wrong about this. Here goes...
I've been under the impression that the chroming process removes a tiny fraction of an inch from the base metal, thereby making it somewhat thinner/weaker. Although it is not really enough to matter. Somebody correct me on this.

Yes, its an additive process. But don't you lose some of the base metal as part of the procedure? Is the chrome plating structural in any way?

Chrome plating has absolutely nothing to do with tubing strength. To the OP, I think you are confusing chrome plating with the use of chromium as an additive to the steel. It's not the same thing. Chro-Moly stands for chromium-molybdenum, and that has to do with the makeup of the metal...your's is chrome plated underneath the paint, which has nothing to do with the other. It is nice though, since you'll have all sorts of shiny spots where your paint flakes off. That's how my wife's bike is.

Chrome is harder than paint, therefore it chips less easily. A lot of older bikes that you see with chrome plated fork tips and stay-tips are plated there to prevent chipping and the attendant rust. Some bikes have a fully-chromed drive-side only chainstay, which works kinda like a chainstay protector.
Often the entire frame was chromed because the process involves dipping the frame in the plating solution, so it's simplest to just do the whole damn thing.
