Can I use a higher or lower speed chain with Shimano ULTEGRA Di2 RIM BRAKE DUAL CONTROL LEVER 2X12s (Left)?
No, Shimano ULTEGRA Di2 RIM BRAKE DUAL CONTROL LEVER 2X12s (Left) requires a 12-speed chain. Chains for different speeds have different external widths and internal profiles, which will cause poor shifting or mechanical interference.

Does the mounting standard of Shimano ULTEGRA Di2 RIM BRAKE DUAL CONTROL LEVER 2X12s (Left) affect drivetrain compatibility?
The mounting standard (such as drop_bars) primarily determines how the part attaches to the bike frame or handlebars. It does not directly affect the mechanical shifting compatibility, as long as the speed and brand standards match.
