Hi hardware hounds:
Amir Avitzur asked about fancy Cyclo ends with tab included...I have a '50's Hopper all made out of the best Reynolds(adopted from e-Chuckie)which has the Cyclo forged ends with hanger and a MarkVII mounted.So that exists.I also have a Raleigh/Huffy in the depths of a shed that has the 60 on it;not sure of the ends.
Jerry Moos wants 3-arm chainrings.The gen setup is a T.A.adapter for 3 arms which takes a pair of the big 6 screw rings.I've got that on a Carlton,so it exists.The commoner setup is Simplex aluminum rings on little steel V adapters(there may even be an aluminum adapter set).Adapters come flat or joggled for French or Italian cranks.Wanna give yourself extra trouble?All these adapter systems exist in rare Magistroni execution also.There was also some wacky Huret multi screwed rings,but I think only in steel(they're hanging over my lathe).
