AXS rear derailleur not aligning with cassette on Amflow PL?

Hi all, aXS gear display no lining up with deraillier gear

I ride a Amflow PL Carbon Pro.

Hi all, aXS gear display no lining up with deraillier gear I ride a Amflow PL Carbon Pro.

Right, @Denf, the good news is this is a known quirk with the SRAM AXS setup on Amflow bikes rather than anything sinister.

First thing to check: there are two alignment lines on the derailleur-to-frame connection point that need to be perfectly lined up. Trail vibration (or a knock) can bump the derailleur body out of position, and if those lines aren't matching, your gear indicator on the DJI display will drift out of sync with what the derailleur is actually doing. You can often just push it back into place by hand.

If the alignment lines look fine, the next port of call is the micro-adjust setting in the SRAM AXS app. It defaults to 7, and shifting it a couple of increments either way (say down to 5 or up to 9) can sort out gear skipping or misalignment under load. Worth doing this with the bike in a stand so you can pedal through the full cassette range while you tweak.

One more thing worth checking, since this catches people out: the SRAM AXS transmission derailleur cage is intentionally bent from the factory. It looks wrong but it isn't, so don't try to straighten it.

If none of that sorts it and you're still getting issues across gears 6-9 especially, it might be worth a firmware reset through the AXS app (sign out, go to off-the-grid/Bluetooth mode, pull the battery, hold the AXS button while reinstalling it). If that still doesn't fix it, a warranty claim on the derailleur itself isn't unheard of.

@Greg Watts I think he was saying the gear indicator on the display is not showing the actual real gear the bike is in. Eg gear is physically in 5 but showing 6 or 7

Right you are, @Rob Rides EMTB. I went full diagnostic mode when @Denf was probably just asking why the DJI display says gear 6 when the derailleur is sitting in gear 5.

Now, there's an important distinction here. The DJI Avinox touchscreen integrates with the SRAM drivetrain and shows what gear you're in.

The PL Carbon Pro runs a wireless SRAM XO T-Type drivetrain, but the base PL Carbon is a different story.

The PL Carbon uses a cable-operated SRAM GX Eagle drivetrain, which is mechanical, not electronic. That matters because the gear indicator on the DJI display gets its data differently depending on which model we're talking about.

@Denf, can you confirm which PL you've got? If it's the Pro (electronic SRAM X0 AXS), the display reads gear position wirelessly from the derailleur.

There's also a shift assist function that briefly cuts motor power each time you shift, but that only works with SRAM AXS shifters.

If the display is out by one or two gears consistently, the DJI system's "SmoothShift" function relies on communication between the motor and the AXS derailleur, so a firmware mismatch or a Bluetooth pairing glitch between the Avinox and the derailleur could cause exactly this. Worth checking the DJI Avinox app is up to date and re-pairing the derailleur.
