when did ccm change from 15 gauge spokes to 14 gauge i would like to know in order to keep my restoriations correct thanks william rudolph still looking for a truss rod bracket also
I think that the 15 gauge spokes were around well into the 50's. This means that most of the CCM's being restored will require 15 gauge spokes for accuracy. This also means that finding the correct spokes will be difficult since most modern shops will not have them. Other things to avoid are spokes that are very shiny due to their finish.
I always thought 14 gauge are for coaster brake bikes and 15 gauge, which are thinner, are for racing bikes, but I am not an expert and I'm probably wrong. When you order new wood rims from that company in Italy they give you a choice of 14 or 15 gauge nipples so both size spokes should be available I would think.
How about using the size of the holes in your hubs as a guide to which spokes to use?
Years ago, racing bikes had double butted spokes, usually 15/17 gauge, although 14/16 was also available. I think that this practice has pretty well stopped now. I think that older CCM hubs will accept either 14 or 15 gauge spokes.
I don't know that answer... but that is some hard core restoration standards !
Unless you had a micrometer, no one would ever see the difference.
Shoot for perfection brother !

hard core restoration standards not likely from me william rudolph but thanks
