Used to tune derailleurs by feel until I timed myself against a Park Tool video

Was rebuilding a customer's old 3x8 drivetrain last Tuesday and realized I spent 45 minutes just on the rear derailleur. Got frustrated, pulled up the Park Tool guide on my phone, and did the next adjustment in 12 minutes flat with a proper hanger alignment gauge. The feel method worked okay for 10 years but I was just guessing. Has anyone else switched to using a gauge and felt like a chump for not buying one sooner?

Used to swear by feel too but the gauge totally made me a believer after one try.

Did you find the gauge helped most with something specific like tire pressure or a particular adjustment? I was the same way @angela_flores but once I dialed in my suspension with a digital gauge, it was night and day different. Now I just trust the numbers and my ride feels way more consistent.

The 32 psi I was chasing by feel for months turned out to be 28 on the gauge. That's embarrassing. So yeah, tire pressure was the big one for me, @angela_flores. I think I was overinflating everything just because it felt "right" when I stomped on it. Suspension I'm still learning because you gotta match it to your actual weight and shit, not just some random turn of the knob. But that gauge saved me from buying new tires every year with the pressure thing.
