1x8 drivetrain is disappointing. Upgrade?
I recently bought an eBike with a 1x8 Shimano Acera drivetrain that after indexing properly is still a bit clunky and sometimes hesitant when shifting from 4th to 5th gear. Sometimes it makes that shift perfectly other times not, it's really finicky. Shifting through the other gears is OK but not anywhere near as smooth as my old pedal bike with a 3x6 Altus.
Would upgrading to a CUES 1x10 make shifting a lot smoother and worth the cost?
Any other thoughts on how to improve performance with the Acera? I'm very good at tuning derailleurs, the bike is brand new and believe the chain line is straight, although I don't have an alignment tool.
