I don’t have many hard rules I follow about specific standards or parts when I shop for a bike, but I do have one guideline I adhere to:

I only buy bikes with online tech manuals containing exploded diagrams, dimensions, part numbers, and torque specs.

I look through the parts and verify that either the manufacturer has spares available on their web store or that they’re common parts available anywhere. I also look up older models and make sure the manufacturer still has manuals and parts for them too so I have confidence I will still be able to get parts in 5 years or so.
