Goal
Quick, repeatable steps to eliminate grinding/rasping by fine-tuning SRAM AXS shifting (MicroAdjust), plus quick battery checks.
What you were trying to solve
- Grinding / rasping in some gears
- Want fine-tune adjustments from the controller (not limit screws)
MicroAdjust (fine-tune trim) — the core idea
- MicroAdjust is for tiny inboard/outboard trim changes to dial shifting and reduce noise.
- Tech tip (SRAM): “Less is more. MicroAdjust one click at a time until performance is optimized.”
How to do it (general AXS controller method)
- While riding (best with suspension in normal sag), press-and-hold the AXS button on the controller/shifter.
- While holding, tap the shift paddle/button in the direction you want the derailleur to move.
- One tap = one micro step. Repeat one click at a time until the noise/hesitation is gone.
Note: Button mapping varies by controller type (Pod vs older AXS controllers). If you tell me which controller you have (AXS Pod, Rocker Paddle, etc.), I’ll tailor the exact left/right button mapping.
When NOT to MicroAdjust
If shifting is wildly off, skipping, or you recently changed parts (hanger, cassette, chain, wheel), MicroAdjust may not be enough—setup/alignment may be needed.
Limit screws (H/L) — when they matter
- H limits travel at the smallest cog.
- L limits travel at the largest cog. Use these only if you’re overshifting into the spokes/frame or can’t reach the end cogs.
Battery quick checks (SRAM Transmission troubleshooting page)
Check battery status
- Press the AXS button on the derailleur and the controller.
- No light = battery is out of juice.
CR2032 controller battery tip (SRAM)
- For best performance, use CR2032 batteries without a bitter child-safe coating ring, which can interfere with contact.
Trailside fallback if controller battery dies (SRAM)
- Use a quick single or double click of the derailleur’s AXS button to shift:
- Single click = harder gear
- Double click = easier gear

What I still need from you (1 question)
Which controller do you have?
- AXS Pod (new Transmission)
- Older AXS controller (paddle)
- Drop-bar eTap AXS
Once I know that, I’ll add the exact button mapping (left/right = inboard/outboard) to this note.
