Classified introduces
SHIMANO Di2 integration

With this announcement, Di2 riders can now shift the internal two-speed Powershift Hub using their existing SHIMANO shift levers. This provides a seamless user experience without the need for additional buttons or remotes, blending the familiar Di2 precision with the disruptive efficiency of Powershift.

The update is free-of-charge and requires no additional hardware. 

This integration merges the advantages of Classified’s Powershift Hub with SHIMANO proven 12-speed Di2 rear shifting. The result is a clean, high-performance 1x setup that delivers instant, under-load gear changes with optimum gearing range and steps.

To set up the Di2 connection, the Classified app is mandatory.

The Classified app is also the only portal to update your Powershift’s Smart Thru-Axle to the latest available firmware. Please make sure you are using the latest version of the app, available on both iOS and Android, to ensure full compatibility and access to all features. 

Installation Guide: how do I connect Di2 and the Powershift Hub?

You can connect your Di2 groupset to the Classified Smart Thru-Axle via the Classified app, and the Shift Button assignment can be changed within the SHIMANO Di2 App (E-TUBE PROJECT Cyclist) to suite personal preference.

Pairing SHIMANO Di2 with the Classified Powershift system delivers a fully integrated, wireless shifting experience — combining the precision of Di2 with the instant gear range change of Powershift, all without a front derailleur.
