Bike IQ 1.2.1: SRAM AXS Shifters and Smarter Estimated Power
A focused follow-up to 1.2 with a big new integration, a smarter power estimator, and a handful of fixes riders have asked for.
SRAM AXS Shifters
Bike IQ now pairs directly with SRAM AXS groupsets. Both 1x and 2x builds are supported, from XPLR gravel setups all the way up to Force and Red D2 road groupsets.
Pairing is a one-time handshake. From the sensor list, tap your AXS derailleur and Bike IQ walks you through it: press and hold the AXS button on the rear derailleur until the LED flashes, tap Continue, and you're authorized. From then on, your phone reconnects automatically whenever you're near the bike, so your live gear and battery data is ready the moment you open the app.
Once paired, every shift is visible in real time in the gear widget, on the ride summary, and on your Apple Watch. Battery levels for the rear derailleur, the front derailleur (on 2x), and both shifters show up in the sensor list so you always know where you stand before a long ride. Gear data is also written into your ride report for every second of the ride, giving you ground-truth gearing alongside your cadence and power afterwards.
For Pro riders, AXS unlocks shifter controls. Both paddles are always mappable. Any extra buttons on your shifters, like the hood buttons on the newer Red and Force groupsets or the bonus buttons on the blip remotes, are auto-discovered the first time you press them and show up as their own rows ready to be mapped. Left and right paddles are tracked separately, so you can give each one its own action. Map them to ring the bell, mark a lap, open the map, or pause the ride, and your hands never have to leave the hoods.
Smarter Estimated Power
If you ride without a power meter, estimated power is going to feel different in 1.2.1. We enhanced the model and tuned its parameters to fit a wider range of riders, and fixed a glitch that could make the number look jumpy.
Smaller Fixes
- Cadence sensors could occasionally report a wildly wrong number on the first packet after connecting and then stay stuck on it for the rest of the ride. Fixed.
- The radar widget no longer goes blank when your radar sensor disconnects mid-ride.
- The power source indicator no longer flickers between connected, disconnected, and estimated during pauses. Whatever source was active when you paused stays active until you resume.
- The gear widget renders correctly on its first frame and dims only the selected gear, not the whole grid.
- A crash in the power curve chart is fixed.
- General mid-ride CPU reductions for smoother operation and better battery life on long rides.
