I just pieced together a crankset to meet this need: Raceface turbine crankset (165mm), Raceface replacement spindle (190/197mm), and a Wolftooth chainring compatible with Raceface Cinch. The hardest item to source was the spindle, but they are out there if you search (there are multiple lengths available, but 190/197 was right for my Farley). Also, this setup has a 30mm spindle diameter, so make sure your frame can take a bottom bracket that will work with that spec.
