I have recently acquired a Raleigh 3 speed with bendix coaster brake Sturmey-Archer hub. This is very much like a bicycle I had as a youngster, but a little different-- It has oil ports on the hub, crank and front wheel and I am wondering what wt oil was used. Normally bearings are greased and I'm thinking that a heavy wt. transmission oil would be appropriate. This is an all chrome cycle with caliper brakes as well. Anybody know about this bicycle?
