Chain Ring Diameters
James Fitch wrote:
Does anyone know, offhand, what the outside diameters are of 53, 52, 51, 50
tooth chain rings? I'm fine tuning a derailleur fit. I'd like to get the
tail of the derailleur dropped a couple of mm to keep the chain from
dragging one rear cog smaller than it does now (currently 53 on the front).

Each tooth is a half-inch. Diameter = circumference / pi.
