  1. Looks like a linkage from a Schwinn Air-dyne that helps connect the crank-arms to the moving handlebars. Probably one of the last hold-outs for cotter pin usage.

  2. It looks like it could be an extender, but it it would run perpendicular to the crankset. You’d have a 90 degree bend in your crankarm, I think. that might look cool.
