For my '38 Paramount, I seek either or both of the following:
10 tooth fixed cog. relatively small chainring to fit 3-arm Paramount cranks. This measures just about 101 mm from bolt hole center to bolt hole center. Rider grade ok; I have a nice one for show, but I'm too old to push a 26x9 on our hills.
Please contact me off-list.
thanks
