Lower back pain on climbs ? bike fit issue or muscular one ?

Hi everyone,

I had a professional bike fit a few months ago which improved my comfort, but I still get a localized lower right back pain when riding outdoors.

The pain:

- Appears after a few kilometers

- Is worse on climbs

- Disappears immediately when I sit upright or ride out of the saddle

- Never happens on the trainer

Other observations:

- Right leg feels dominant

- Bib shorts wear more on the right side

- No knee, hip, neck or hand pain

- Core strength is not great (~30s plank)

Do you see anything unusual in my position, pedaling mechanics, saddle stability or pelvic movement that could explain it?

Thanks!
