Elite Sterzo smart steering add-on for indoor cycling. I used this with Zwift to give a more realistic ride.

Need 3x AAA batteries. Used - I have tested it to ensure its all in working order and able to connect via Bluetooth.

From the manufacturer:

Sterzo Smart is Elite’s steering plate that makes indoor training more realistic and engaging. 

Placed under your bike’s front wheel, it connects via Bluetooth® to Zwift and turns every handlebar input into real on-screen movement for your avatar.

Steer, pick your line, sit in a wheel, and make passes. An immersive experience that adds control, strategy, and fun to your indoor rides.
