That's pretty close to the ground. And those are 40/355. 35/349 are a lot smaller and lower.

From that link it looks like that's just the hub weight. And that hub has got to weigh way more than a BWR. From Google's AI:
A Rohloff Speedhub generally weighs around 1.8 kilograms (4.0 lbs). This weight is for the hub itself, without shifters, cables, or other components like a belt drive or cogs. The total weight of a complete Rohloff system, including the hub, shifter, and other components, can be roughly 2.4 kg (5.3 lbs).
Sorry,I'm not convinced.
