Precision, Power, and Performance
Classified Cycling Torque Arms brace your Powershift hub against your bike so you get unrivaled shift quality, high gearing range and small steps in between gears combining the benefits of both 1x and 2x drivetrains.
Powershift Technology is a wireless shifting technology that allows you to shift gears instantly and under full load. The Shift button sends signals to the hub via the Smart Thru Axle, which then shifts between 2 ratios, similar to shifting a front derailleur between big and small chainring.
Please see Classified's Torque Arm Guide to ensure you get the correct option for your bike.
