How it works


Shift button

The satellite shift button triggers a shift and is attached to the Smart Handlebar Unit, sending out a wireless signal. Gear selection of the virtual big and small ring are visible from Wahoo/Garmin head units.


Smart thru axle

The Smart Thru Axle receives the wireless shift signal and triggers the hub to shift using contactless energy transfer.


Powershift hub

The hub receives the signal and shifts between 2 ratios, similar to shifting a front derailleur between big and small chainring.
