Jeff Jones' bikes seem to be the business for off-road bikepacking, Pete. I recently read a very positive review of one of his bikes in Bicycle Quarterly, though that machine didn't have a Rohloff. I seem to recall that toe overlap was a problem with the front wheel if it was equipped with a mudguard; but again, the test bike didn't have 29x3 tires. Enjoy your Aotearoa off-road trek!
