stem and handlebar sizing

Hi guys,

I need some help figuring out stem and handlebar sizing.

I know I need 1 1/8th threadless, but as for clamp and handlebar diameter, I'm seeing numbers like 25.4mm and 31.8mm. Am I correct in assuming those measurements are for only the center of the handlebars, which then taper down to whatever the standard brake lever/grips/shifter diameter at the handlebar ends?

What's the standard on size for all the handlebar accessories that I mentioned above? I seem to recall something like 7/8". TIA

Not sure about brake / shifter clamp zone, but the standard stem/handlebar clamp diameter is 25.4mm. OS is 31.8mm. OS is becoming pretty standard.

I like OS just because it looks flippin RAWK! With a good bar and stem, you'd be hard pressed to actually "feel" a difference unless you're senses are acute and you're a monster. I think 25.4mm is plenty adequate, but I'll probably never willingly choose it over 31.8mm because OS looks flippin RAWK!
