bicycle anatomy 102

"Parts is parts" as they used to say, but I need to find out what the heck everyone else calls them. I was surprised to learn that the rotating shaft that the pedals rotate around is called the bottom bracket (I could maybe see calling the race a bracket, but the shaft? What kind of engineer named that?), after confusing the guy at the LBS by calling it the crankshaft. And while he did seem kind of amused by my calling the crankarms conny rods, I'd rather learn the lingo that find out how little else of my internal combustion anatomy transfers to bicycling. I looked here on the site for more information, but haven't found any yet. But I did finally find out just what OCP stands for! Is there a site for the nomenclature? I doubt I'm the only one looking for this information?

You are correct the BB is the part of the frame that all this stuff goes in, but the term is also used for the assembly of the bearings and shaft. The con rods are usually called legs in the bicycle world.

go to this site if you want to know what a part is called: http://www.parktool.com/repair/

go to this site if you heard a part name and want to know what it is:

Also , What's an OCP? or did you mean OPC- one piece crank

That part of the frame is not called the bottom bracket, it is the bottom bracket shell or hanger. This causes a lot of confusion.

Crank legs? More like crank arms.

Thanks for the advice, that was just what I was looking for! And OCP is defined here: Can we get a sticky in the Road Forum for "What is OCP?" the laughs I got from this were a great way to start another day in my fashion impaired life.
