It's lighter & stronger than steel.
It doesn't vibrate, at any speeds.
It's made from the highest quality carbon.
It can still flex.
The weight loss is a secondary benefit.
Each driveshaft is individually tested on YFCM's proprietary machine. They are spun to over 8000rpm as a complete assembly.
The flange is a self-locking, sealed design: it locks over the carbon tube. It eliminates all probabilities for the tube to spin free of the flange, no matter the torque.
Been there, done that.
