Chain sizing guide
- 3/32" = 2.38mm - width of the chain opening
- 1/8" = 3.18mm - width of the chain opening
- 1/2" = 12.7mm - width (pitch) between the chain links
- A 1/8" chain will fit on 1/8" & 3/32" Freewheels & Chainrings
- A 3/32" chain will only fit on 3/32" Freewheels & Chainrings (as it is not wide enough to go over 1/8" teeth)
