Chain too long or something else ?
Picked up this bike the other day. Rode great.
Shimano 105 group
9 speed
Changed tires today and noticed chain rubbing see pic
This happen on another bike last year and it was the chain that was too long.
Big chainring no issues
Appreciate any and all help

Yea, too long. In the big/big combination, the derailer should be closer to horizontal. You are also rubbing before you get to the small/small combination. You likely need to remove 3 rivets. Yellow arrow points to rivet 1 (it’s already removed). Red arrow points to rivet 3. It could also be seen as one link if you consider a “link” to be an inner and outer plate.

Shift into the small/small combo and the pulley cage should look slightly less horizontal than the first photo. Also try the big/big combo with the new chain length just to check if there is enough slack but I highly doubt it would end up being too short for your bike.
Looks like cyccommute beat me to it. Agree with what he says.

Thank you BOTH!!
That's what I thought, but wanted to make sure.
The last pic it's in BIG / BIG
RD looks pretty horizontal**********
Really appreciate the expertise help.
So should I start with one / two links ?
Because once removed cannot put back.....correct ????
Again really appreciate the help.

Thanks again to ALL!!!
That part looks like a paper clip😁😁😁😁😁
I can move the chain from the small chainring and rest on BB to adjust chain.
I do this when removing wheel to make it easier as well 😁🚲🚲
Appreciate your time and expert help and knowledge 🚲🚲🚲🚲🚲
I'll remove one link at a time. I'm on the cautious side 🙂
