Art 7 days ago Share Tweet Pin Share 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.
