New chain issues

[Brookert]

I've got a brand new SRAM 9 speed chain to replace a very old stretched one. The problem is, when I cut it to approximately the same length as the old one (taking into account the stretch), the highest gear causes the chain to rub on the derailleur when on the lowest front chain ring.

Take another link out you say? Well when I do that, it's too tight in the lowest gear and highest on the front chain ring. The derailleur leg is fully extended and causing resistance.

Any suggestions?

As in smallest cog front and smallest cog back. The chain rubs against itself from the cassette to the derailleur. This suggests it's too slack.

Take a link out and that problem is solved. Put it in largest front and largest rear and it's then too tight.

Is it just asking too much to expect the extremes to work. Odds are you'd never use those gear combos, at least the lowest ones.
