While wireless derailleurs may offer fast and precise electronic shifting, the things ain’t cheap. That’s where the NXS system comes in, as it’s promised to make existing cable-actuated mountain bike derailleurs wireless for less than eighty dollars.
Yeah true. Zerode bikes are taking it on. I have an older zerode with a heavy shimano alfine gearbox but the new ones are integrated with a belt instead of a chain as well.
