July 13, 20187 yr http://www.cyclist.co.uk/news/5002/no-chain-no-mechs-no-problem-the-new-ceramicspeed-driven Wonder how much it will cost?
July 13, 20187 yr Author Wonder how much it will cost? I have been looking at some of the really really cool stuff on offer and as I also need to ask how much then I cant afford it!
July 13, 20187 yr I have been looking at some of the really really cool stuff on offer and as I also need to ask how much then I cant afford it! Couldn't agree more. Just an outside hope that the price might drop in a few years - but if it starts at 10k+ (as per soundwave), I'll be dead long before I could afford a bike fitted with it.

July 13, 20187 yr custom built race bikes are 10-20k depending on make so it wont be on the crimbo list for a very long time yet at a price most could afford. i dont think anyone on this forum even has a 10k ebike
July 13, 20187 yr It's a concept and many think it will stay a concept. On the other hand you can buy a 1 x 13 speed transmission. If you can afford it...
July 13, 20187 yr Why? Are you very old or very poor? Whilst I could choose to spend 10k+ on a bike, it is more than I would be willing to spend. Might be happy to throw an extra £500 at a bike with that feature. And, if 10k+ were the current cost of CeramicSpeed, it will take a long time to drop to £500 or below. Even if 10k+ were a complete bike fitted with CeramicSpeed, it rather implies a hefty premium.

There are some really cool products on show and the future is definately electric but its now at the point where a purchase might soon be buyers remorse when next year's tech becomes available.
July 13, 20187 yr modern implementation of a 120 year old idea. Still brilliant though. http://cdn.road.cc/sites/default/files/image_1256.jpg
July 13, 20187 yr if you paid 1 million quid for a cray super computer 12 years ago today it is scrap!

There are some really cool products on show and the future is definately electric but its now at the point where a purchase might soon be buyers remorse when next year's tech becomes available. Looks like Rohloff start at about £900. Take off the cost of whatever would have been fitted (what? £300 for some Shimano or SRAM) and you are not that far off £500 extra. (Yes, I know, you have to fully list every component to get a proper assessment. I am not a bicycle builder and have just grabbed some online prices.) And with anything, if you go for the top end, it could be much more.

I am in a negative mood and am Mr disillusioned right now having found out that the bike I would like to buy weights in at 31kg.
July 13, 20187 yr Not bad. I would like a rohloff myself but at £1000 it would need to last 8-9 years before it saved me any money over buying 2 chains and a slx cassette every year.
July 13, 20187 yr They say no plans to bring it to market, I'm not surprised. I can see it could prove rather fragile. .
July 13, 20187 yr They say no plans to bring it to market, I'm not surprised. I can see it could prove rather fragile. . "At this stage, however, there are no plans to bring the system to the consumer market." You could interpret that statement in many ways. For example, if they have decided to go down the licensing route - any plans wouldn't be theirs. Also, being specific about "consumer market" could mean that it will appear on professional racing cycles. I'd be a bit concerned about its ability to cope with rain and mud, as it is. Looks like the bearings are rather exposed. But what do I know? Precisely nothing.
July 13, 20187 yr Could see market for it in professional road racing. For ebikes better of using higher loss shaft drive systems from motorbikes. With ebikes , especially commuters low maintenance and reliability is far more important than efficiency.
July 13, 20187 yr Can’t see it lasting even if it was brought to market One thing that struck me straight away was the side loading that rear cassette is going to have especially on the larger rings the curved drive wheels and curved cassette is naturally going to force apart underload as there’s going to be flex on that rear cassette no matter what .
July 13, 20187 yr Could see market for it in professional road racing. For ebikes better of using higher loss shaft drive systems from motorbikes. With ebikes , especially commuters low maintenance and reliability is far more important than efficiency. Quite possibly you are right. However, increased efficiency helps enhance range. Also, didn't they claim a significant weight saving as well?
July 13, 20187 yr modern implementation of a 120 year old idea. Still brilliant though. http://cdn.road.cc/sites/default/files/image_1256.jpg The old one is far superior we’re still using pinion drives today with high success:)
July 13, 20187 yr I'd be a bit concerned about its ability to cope with rain and mud, as it is. Whilst I still know nothing, I have now read this: FURTHER DEVELOPMENT options for Driven can include, a double row ball bearings (further increasing the efficiency levels), a more optimised, possibly asymmetrical tooth design, material testing (advanced lighter and durable materials for the rear cog and front ring). The patent includes the possibility for a powermeter inclusion inside the shaft and a compact shroud can encapsulate the entire drivetrain to protect from mud, rain, and contamination https://www.ceramicspeed.com/media/2979/driven_brochure.pdf
July 14, 20187 yr Quite possibly you are right. However, increased efficiency helps enhance range. Also, didn't they claim a significant weight saving as well? I am not convinced that directing torque through 90 degrees (twice) is any more efficient than a well maintained roller chain. And it is unlikely to be lighter when you factor in the additional weight (strengthening) needed to deal with sideways thrust loads. You only have to look into why all road sports and race motorcycles still use chains and sprockets. Avoiding side loads is also why straight cut gears instead of helical are used in race cars. Whoever designed this bicycle system may have solved/minimised the above issues but I remain sceptical.
