That depends on the bike - Typical 3-speed, ss are 1/2x1/8"

For the 5/6 FW's, it's 1/2x3/32"

IT goes from the front of the spiky wheel thingie to the back little spiky wheel thingie, around, a couple smaller, spinny spiky wheel thingies and back to the front thingie. Are we talking LINK size, or chain length? Working on a chain length issue with my son's newly acquired 86 Team Fuji. Just put the chain on right out of the package...it is a bit long, so we are trying to determine how many links we need to remove for proper functioning. (We replaced the tired, very bent back wheel with a 105 9 speed)

Well, the pitch (except for the old Dura-Ace 10) puts it in the 40 series, but I'm not sure it conforms in width and roller diametrer.

Edit: Apparently it does conform to 40 roller diameter but not width.

From Wikipedia:

The chain in use on modern bicycles has a 1/2" pitch, which is ANSI standard #40, where the 4 indicates the pitch of the chain in eighths of an inch, and metric #8, where the 8 indicates the pitch in sixteenths of an inch.
[edit]Width
Chains comes in either 3/32", 1/8", 5/32" or 3/16" roller widths: 5/32" is used on cargo bikes and trikes, 1/8" with low-cost coaster brake (back pedal) bikes, hub gear and fixed gear bicycles, and on track bikes. (Fixed sprockets and freewheels are also available in 3/32" widths; fixed gear and single-speed bikes can be set up to use either 1/8" or 3/32" chains.) Derailleur equipped bikes such as racing, touring and mountain bikes use 3/32" chains exclusively.
The Wikibook, "Bicycle Maintenance and Repair", explains that the difference between derailleur chains commonly labelled 8-speed, 9-speed, and 10-speed is in its external width (all are 3/32" chains, that is, in their minimum internal clearances).

I was wondering if this 1/2"x11/128" would it fit on my bike that uses 1/2"x3/32"
