Bicycle Handlebar Diameter
Bicycle handlebar or often bicycle handlebars refers to the steering mechanism for bicycles; the equivalent of a steering wheel.
A straight line passing from side to side through the center of a body or figure, esp. a circle or sphere
In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the circle. The diameters are the longest chords of the circle.
A transverse measurement of something; width or thickness
a straight line connecting the center of a circle with two points on its perimeter (or the center of a sphere with two points on its surface)
the length of a straight line passing through the center of a circle and connecting two points on the circumference

I still have the narrow chain and Surly stainless steel 48t chain ring. I had a 3/32 Dura Ace cog that came on the bike. I know the 1/8 chains and associated gears are stronger, but in reality, do I need to change over?
The chain ring is stainless steel! I wish Surly made them in 1/8, that would be awesome. I know the important one is the cog, which being much smaller, has fewer teeth in contact with the chain. If I were pounding on the bike all day like I used to as a messenger (oh, I miss those days!) then I would make the change.
The cranks are cheap but seem OK. They have a 130 mm bolt circle diameter instead of the more track-specific 144mm BCD. I'm limited with chain rings, but luckily, TA Specialites makes a very nice ring and NYC Bikes in Brooklyn sells some lesser-quality but inexpensive rings with an odd offset of sorts which makes for a good chainline.
One advantage of the fatter chain are the cheap but strong KMC chains that come in colors. I can have a red chain again.
