Just ordered a bottle from Stansport. It is nice but much smaller in
diameter than my California Bike Gear bottle which is a snug fit. So the
Stansport bottle rattles around in there.

Why can't they agree on one standard diameter? In the electronics
industry we got that licked decades ago.

Any tricks how to adapt to both without bending the cage back and forth?

A standard bicycle water bottle is 2.875" (73 mm).

There are cages available for larger bottles. I have the best large cage
on a couple of bicycles. It means one bottle instead of two. It's also
extremely secure. It's item #1 on my page at
http://tinyurl.com/notatlbs. There is also a cage for a growler (#3).

I recently saw adjustable diameter cages that us a rubber strap, at
Target and Walmart. Secure, but time consuming to get the bottle in and out.
