Do these mirrors fit my handlebar diameter?

These use standard handlebar threading. Measure your mirror boss — most bikes use 10mm or 8mm. Test-fit before tightening to confirm proper engagement with your specific setup.

Will the chrome finish stay shiny, or does it need maintenance?

Chrome holds up well in normal riding, but salt spray and hard water can cause spotting. Wipe them dry after rain or wash, and they'll keep their shine for years.

Can I adjust the mirror angle after I install them?

Yes. Both mirrors swivel once mounted, so you can dial in your sight lines exactly how you need them without any tools.
