Bike part manufacturer CeramicSpeed has developed a drivetrain concept that uses an advanced drive shaft without any chains and derailleurs. Partnering with the University of Colorado’s Mechanical Engineering Department, the team was able to create a design that halves the friction of traditional chain and derailleur setup.
It uses a carbon driveshaft that turns two sets of bearing pinions that shifts torque effortlessly from the front ring through the drivetrain and onto the flat 13-speed cassette. This also means that the efficiency rises to an extraordinary 99%. It also features near limitless gear ratio options and a unique carbon fiber shaft-driven bearing gear that results in a more durable system.

No chain, no derailleur, no problem! . This insane @ceramicspeed Driven Concept drivetrain uses a carbon driveshaft turning two sets of bearing pinions to shift across a perfectly flat 13-speed cassette! . They say it’s drastically more efficient than the traditional chain-driven system, and has almost limitless gear ratio options, is lighter, and more aerodynamic! Is this the future of bicycle drivetrains? . Full story on Bikerumor.com now! . #prototype #ceramicspeed #cycling #roadbikes #eurobike
