It's a 2016 Kona Sutra LTD. Basically the gravel bike version of the Kona Sutra touring bike with hydraulic disc brakes and a SRAM 1x11 groupset. Mine has clearance for up to 50mm tyres, but from 2017 they modified it to fit much wider tyres.
I really rate them, not a common bike at all, but really comfy to ride long distance as befits a touring bike, but really capable off-road as well. I've heard them described as a rigid, drop bar 29er mountain bike and it's not far wide of the mark.
