No chain and gear turned "upside down". Ceramicspeed has developed a bicycle concept that they believe will revolutionize cycling.
In the case of bicycles, the development of "transmission" has been fairly traditional. Properly, the gear systems have been improved and various forms of power transmission have been tested. But overall, nothing has been possible to challenge the classic chain system
But now, it is a concept that can really accelerate development.
From eight to two points with friction
This is the Danish company Ceramicspeed which, along with the engineering engineer from the University of Colorado, has made an alternative to a new system of chains.
And this should not only weigh less but also be less bulky and less resistant to air. Conventional drive chains (tested against the Shimano Dura Ace)
This is done by removing the chain with its eight different dots where slip friction occurs and replaced it with a d & rsquo tree. Training that has only two points. – In terms of efficiency, it has a 99% efficiency at 380W, says Chief Technology Officer Jason Smith in Ceramicspeed, at Road.cc.
G The replacement will take place electronically
The concept that was presented at the Eurobike fair had either one or 13 gears, but adding more should not be a problem. Gear shifts are thought (it is not a finished product as they say) electronically where the battery, the servo and the wireless receiver are in the drive shaft
Speed changes will not be done directly. gear changes – a bit like an automatic gearbox in a car. But Smith says it will be perceived as "almost immediately".
– Ceramicspeed is proud to have done something that many said they could not do. We achieved 99% efficiency in a multi-rig system while we removed the complex chain and rear gear.
– & # 39; Driven & # 39; is a real revolution with the unique power transmission and efficiency. The concept can certainly change the way the bike industry looks at the design and efficiency of aisles, "said Jason Smith.
It should be noted however that this is not the first training tree system developed for bicycles. Already in the late 1800s, many experimented with technology, and in the 1900s various alternatives were also introduced. But none of them has been as effective as the Ceramicspeed shows now.
