Ceramicspeed “Driven” chainless drive

Since cycling has a 150 year history, it’s rare to see a truly new idea. Here’s one: a chainless drive system that claims to be 99% efficient, compared to 95-97% efficiency for a bicycle chain drive.

Ceramicspeed is showing a concept that could replace the bicycle chain and derailleur system. It’s supposed to be similar in weight to a top end gear set and derailleur. For touring and bike packing, the chainless system could be enclosed, or at least shielded better than the chain driven system. And the gearing could be close, evenly spaced ratios, while having extended range. Interesting!
