How does it compare with the rohloff system?

Anyways it seems to be significantly more expensive thus I don't think it will become widespread.

I enjoy the rohloff system. I use it with the gates centertrack belt drive instead of a chain.

The rohloff system is quite heavy though, so I don't know if it's "more efficient" than a traditional high end sprocket-and-chain system. The rohloff also shifts the weight to the rear of the bike. Maybe the pinion gear box system might be better since its weight is low and towards the center of the bike.

It's not more efficient than a clean derailleur transmission but less maintenance. The trouble with derailleurs is dirt.

You are not referring to rohloff, but the gates carbon drive, which is amazing technology. Rohloff works with either a chain or a belt.

I sure hope it's cheaper than the Rohloff hub, I can't imagine anyone buying these if they are very expensive. I thought I had read that chains and sprockets were pretty efficeint in terms of energy loss.

It's the chain not the internal hub. Rohloff can use either a chain or a belt drive. The belt drive is cheap, and works with other internal hubs (sealed planetary gear system), which are much cheaper (e.g. Shimano, others make them).

Tourers buy them. Money well spent. Just change the oil every year. Less efficient than a clean deraileur drivetrain but those stay clean for about 30 minutes.

Apparently well adjusted modern gear can be 98% efficient.

This is a chain system, to transfer power from the bottom bracket to the wheel. AFAIK, Rohloff is gear system built inside a wheel hub. How would one compare those?

You are right. Perhaps he meant if it can be used with the Rohloff system or not.

It can be used with the Rohloff system. But, I think you need a compatible chain ring since they are talking about a new tooth design requirements. The Rohloff system has the chain ring attached to the hub gear. So you presumably have to change that chain ring yourself.
