Road bikes are pretty much 100% metric. Headsets are 1" or 1 1/8" though....but that's about it. Everything else is mm or cm.
Mountain bikes, with their American heritage (mountain bikes and BMX bikes were American developments) are inches a lot of the time and are more apt to be weighed in pounds.

I posted a message a week or two ago about how bicycles are pretty much entirely metric. I still believe that is the case with respect to the various fasteners used. However, clearly it is not the case with respect to general measurements. Check out the attached clip from a catalog. It includes: millimeters centimeters fractional centimeters inches fractional inches pounds
In the same catalog, wheel masses are in grams (640 g, 820 g, etc.).
This is from the Nashbar catalog, http://www.nashbar.com/.
