If it gets harder...shift to easier. If it's too easy...shift to harder. When you run out of gears either work harder or get off and walk. If you run out of gears going down a hill..start coasting. Doesn't matter what gear you are in...just shift whenever necessary. Gear indicators quickly become irrelevant to riders as they gain familiarity with their bike.

I've had them in the past on bikes in the 80s and 90s and that was with 3x drivetrain...never used them.
How do you know you're in a good gear combination if you can't match that feeling in your legs and lungs with changes in your speed?
