Fairly sure it's said somewhere on the Soma site that the Wolverine isn't intended to be run with 650b wheels (not that you can't of course). The BB isn't super high and the geo is based around running large volume 700c/29er tyres already. You'd need very large 650b tyres to match that and keep the BB height up and I'm not sure it has the clearance to fit what would be needed.
