What is the Smallest Bigring......

[97CSI]

What is the smallest bigring that will fit on a standard Campy double crank? Want to use for building my single-speed Paramount.

I know it's meant to be a inner ring on a double, but would a 42 tooth 135mm BCD work on the outside?

probably. you could go all the way down to 39t.

check out TA's Horus or Vento Rings- looks like you can go down to a 49 or 50 if you are looking to retain a usable double

I would guess a 39 if you are running a single chainring
