DTI: Digital Tech Intelligence

Enclosed and protected in the Power Unit™ and interface, "Digital Tech Intelligence" transmits, receives and processes data thousands of times a second.

An electronic brain which instantaneously synchronises all the functions requested by the rider. With just a simple click of the controls, D.T.I™ transmits the corresponding signal instantly, accurately and reliably to the rear or front derailleur, for levels of performance and control feel never experienced before with a conventional drivetrain.

But as well as all this, the D.T.I. system also monitors the entire drivetrain and each of its components, continuously checking battery level and functionality, and checking that the rear and front derailleur are working correctly.
