Those would work, but I think Fietsbob was referring to something like the Jagwire barcon 2.0 mounts. They keep the bar end shifters as bar ends instead of thumb shifters. You put the bar end shifter on the Jagwire mount. The mount goes around the bar instead of inside the bar like the Shimano does. They come with a shim so they can be used on 22.2 bars.
