Looks cool, but what's the advantage of having air lines instead of cables?
It shifted perfectly once setup, no cable stretch, really quick push button effortless shifts, but there were to many downsides (cold, altitude, 500 shifts, cost etc). I think the main advantage was with the big dh rigs back then like Karpiels, the rd wire cable route was just crazy and always ended up with a sluggish shifter feel, so the airlines solved that
