About Classified Powershift Technology.
Classified Powershift Technology is a wireless shifting technology that allows you to shift gears instantly and under full load. Its first application is the Powershift hub, which replaces the front derailleur. The Powershift hub offers unrivalled shift quality, high gearing range and small steps in between gears combining the benefits of both 1x and 2x. The Classified Powershift system is made up of 3 main components.
Classified Shift Button.
A satellite shift button will trigger a shift and is attached to the Smart Handlebar Unit, sending out a wireless signal.
Classified Smart Thru Axle.
The Smart Thru Axle receives the wireless shift signal and will trigger the hub to shift using contactless energy transfer.
Classified Powershift Hub.
The Powershift hub, when receiving the signal, will shift between 2 ratios. Read more about gear ratios.
Classified Virtual Gear Ratios.
The ratio is similar to what you'd find on a 2x-setup. The ratio is roughly equivalent to 53/36, 50/34 or 48/33 chainrings for example.
The hub has two speeds. In Direct Drive it is 1:1; meaning the cassette and hub have the same speed. In Under Drive it has a ratio of 0,686, which means that for each revolution on the cassette, the wheel rotates 0,686 revolutions. We call this 0.7. Under Drive effectively replaces the smaller chainring on a regular 2x-crankset.
