I still find it amazing, after all these years, that when this subject comes up, how few have actually bothered to install an actual chain-counter. There are a number of quite inexpensive ones out there easily installed by ones-self. There are expensive fancy ones too - ones that actually park themselves and are virtually hands-free, but the simple ones are still amazing.
Having done so - and also been through the painting, zip ties, coloured whatever, I would never go back to that after having a chain-counter. Just sayin'...
y'all will still go on doing all that, I know, but the OP might not have thought of it - and just might do himself a favour and do it..? Even if not right now, but later on..? This is what I used - a lot of fun getting it done too.
