Its a Rolhoff - if that doesnt expalain the shifter then you should start googling
But surely enough people are putting Rohloffs on drop bar bikes that Rohloff should get their arse in gear and make an integrated shift/brake lever for road bikes, preferably a cable version and a version with an hydraulic master cylinder so quasi-CX bikes can start using grown up callipers. Having the shifter right at the end of the drop is about the worst place it could be given that off road riding demands accurate steering, braking and shifting all at once.
