A masterpiece of engineering

The Classified hub houses a wireless electronic shifting system developed to confidently shift on any terrain, anywhere, anytime and under any circumstance. It integrates a great deal of smart technologies.

Smart Hub Technology

Shift within 150 milliseconds under full load with the Instant Power Shift (IPS) Technology. The Efficient Actuation System (EAS) Technology enables shifting with only 1 Watt of power for a stunning 1,000 Watt powershift, resulting in over 10,000 shifts on a single battery charge. The removable hubshell allows you to freely exchange the hubshell without changing bearing preload, that way you can easily change wheelsets.

Smart Thru Axle Technology

Classified hubs feature a smart wireless thru axle which wirelessly transfers energy to the smart hub for actuation via induction coils. The smart thru axle wirelessly communicates with the handlebar unit to receive shift commands, while the ANT+ integration communicates your current gear ratio to your bicycle computer.

Driver and Frame Interface Technology

Our driver integrates Hyper Size Driver (HSD) Technology. Resulting in ultimate strength and minimum wear, due to torque on large radius. Also, the double ratchet system guarantees ultimate strength and lifetime, through the independent ratchets for the large gear (1:1 ratio) and the small gear (0,7 ratio).

The Integrated Torque Support (ITS) allows for an integration of the torque support in the bicycle frame, enabling an easy installation of the thru axle. The External Torque Support (ETS) provides torque support without any modifications to the frame allowing fast application of the product.

Cassette Technology

Classified one-piece steel cassettes are processed with high durability coating for low wear. Due to the larger driver interface, the cassette does not require a spider. This results in extremely durable & light cassettes.
