I think you mischaracterized my meaning of "replaceable bikes". I don't mean it in the way where they get rebuilt unnecessarily, but the fact that pro teams get practically brand new bikes every year (or at least every time the sponsor/manufacturer releases a new model), is the meaning I was going for.

Also it's easy to say "use your brain" for those of us who are careful and know what to look out for, but if the intent is to convey advice to random strangers on the Internet who may read this message days/months/years from now on, I'd prefer to err on the side of caution and don't assume they'll be competent enough to direct the high pressure jet appropriately and responsibly (not referring to the OP, but this is a public forum and any Tom, Dick and Harry can find and read it, after all).
