I have an old bike setup for Café riding. It came with a 52/40 Strong light crank with an integrated chain guard. A nice option as I can wear regular street clothing when biking to and from stores and of course, Cafés! Mustache bars are an absolute (fashion) necessity with this style of bike! Here is a photo of my setup using thumb shifters in place of Bar-end shifters, which I find more convent as they stick out the side of the bar instead of in-line with it so I can palm the shift levers.





Note the use of cork plugs in the bar ends for that old school look.
