Works with Shimano Di2

Your Di2, live on your iPhone

Bike IQ pairs straight to your Shimano Di2 groupset. Your gear, your battery and every shift show up on the ride screen, with no head unit in between.

Free. No ads, no account.
The Shimano Di2 screen in Bike IQ: connected to a Shimano Ultegra Di2, system battery at 82 percent, big ring and cog 7 of 12, and the left and right hood buttons mapped

The strip across the top of every Bike IQ page, lit the moment you shift.

Pairing Di2, live gears and battery are free. Turning your shifter buttons into controls is part of Bike IQ Pro.
