What about potential of the ceramicspeed driven design? https://www.ceramicspeed.com/en/driven/ https://www.ceramicspeed.com/en/driven/
- TwoBit 6y agoI cannot believe that thing is viable.
- S_A_P 6y agoIt appears that it currently is not...
- FpUser 6y agoSome cyclists are indoctrinated to the point that they might actually buy this insanity.
- rorykoehler 6y agoHN is becoming more conservative by the day. Shouldn’t companies/people be applauded for thinking outside of the box and trying to innovate?
- Kliment 6y agoInnovation can be good, scamming other people into spending money on things that don't work, not so much. There's a whole lot of the latter masquerading as the former. There's also a whole lot of user/customer/community hostile innovation, like the entire advertising industry.
- rorykoehler 6y agoThat’s not the case here though. The design I linked is a legitimate attempt at solving a real problem. Whether it works as well as intended or not is a separate issue.
- FpUser 6y agoThe design as plain obviously wrong. The only "legitimate" part there is trying to part people with their money for zero benefits.
- rorykoehler 6y agoI'm not a mechanical engineer or anything remotely like it. Can you explain why the design is wrong and especially explain why you think it's a dead end that can't solve it's problems via iterating?
- FpUser 6y agoThis drive train simply can not handle high torque as the chainrings will bend under load. They admit it themselves. Increasing their thickness will cause a whole lot of compatibility problems and also turn the whole thing into a monster. This expensive ceramic bearings are exposed and will experience significant wear. Properly insulating them would wipe out whatever miniscule gain in efficiency they claim as the insulation increases losses. Finally reducing chain friction (which is already very low on a tuned drivetrain) to some fraction (that has yet to be proven for real conditions) is tantamount to snake oil in my opinion. These are just few. I could go on but it is not worthy the typing and mental efforts.
