## 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)
1. While riding (best with suspension in normal sag), **press-and-hold the AXS button on the controller/shifter**.
2. While holding, **tap the shift paddle/button** in the direction you want the derailleur to move.
3. **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.
