It's a cable-free radio controlled gear-changer for the Rolloff. There a switch box on the handlebars, suitable also for drops, no cable whatsoever, and a stepper motor box to be fitted to the Rohloff in place of the EXT klickbox.
Pricey but if you gotta have a clean show bike, or you can't get a smooth cable run on some weird bike, or you're just a gearhead, or of course if you have drops and hate the gear control being so far away, it could be worth the money.
