1 Handlebar unit The wireless handlebar unit is installed into
the left-hand side of the handlebar and is
controlled by a shifter or satellite buttons
compatible with Classified. The handlebar
unit is powered by a battery.
2 Smart thru axle The smart thru axle receives the wireless
shift signal from the handlebar unit

contactless energy transfer. The smart thru
axle is equipped with a rechargeable battery.

3. Principles of operation
3.1 The operation of the Classified Powershift hub
Through a compatible shifter or satellite button, a shifting command is sent to the handlebar unit. The
handlebar unit wirelessly transmits the shifting command to the smart thru axle using Bluetooth. The
smart thru axle transfers the power needed for shifting and the shifting command to the Powershift
hub. The shifting takes place internally within the Powershift hub.
The smart thru axle transmits your current gear ratio and battery status to your GPS bike computer
(not included) using ANT+.
The Powershift hub has 2 gear ratios:
•A 1:1 ratio, where the speed of the cassette is equal to the speed of the wheel. This is similar to the
large chainring on a traditional 2x.
•A 0.686 ratio (reduction ratio), where the speed of the wheel is lower than the speed of the
cassette. This is similar to the small chainring on a traditional 2x.
Shifting from 1:1 to the reduction ratio is like shifting from the large to the small chainring on a
traditional 2x.
