perfect for trail centre riding
well there’s your limitation, right there.
I’ve been riding a Rohloff for 4 years now. /once you learn to cope with the different weight distribution, the advantages are immense.
I’ve also had an alfine-8 which was good, but nothing compared to the Rohly, and still ride SS also.
2 and 3-stage BB/crank mounted gears could be useful if they’re cheap enough to be combined with a cheaper hub-gear. i remeber people talking about combining the Hammershmidt with an Alfine. Sure it gives the spread of gears of a triple setup, but for the cost and weight of a Rohly with added complexity. And sadly Shlumpf drives aren’t uch cheaper.
Most exciting thing I’ve seen is the Pinion gear-box. Would love to give one of those a go. especially on the Nicolai they’ve built for it. If only they could figure out a way for a concentric main pivot, then it could go belt-drive too…..
Edit – just watched the video again. Massive advantages for city bikes, and could realistically replace a triple chainset if its cheap enough….
