PSA: My old way of checking door hanger rollers was costing me hours
For years, I'd just give them a wiggle and a visual check, but I kept getting callbacks for noise on the same units. Last month on a job at the old Granville Hotel, my partner showed me his trick: he uses a dial indicator to measure the vertical play. Found one roller with 0.08 inches of slop I'd have totally missed. How do you guys check them to be sure?

What kind of dial indicator does he use? That's a solid trick. I've been burned by the wiggle test too, it just doesn't catch the small stuff. I might have to start carrying one in my kit.

A dial indicator is great for sure, but you need a solid magnetic base to make it work right on most frames. OliviaTorres is right about the wiggle test being a trap, it gives a false sense of security. The real trick is checking the headset with the front wheel off the ground, you see movement you'd never feel. Just make sure your indicator can read in both thousandths and millimeters, some older bikes mix units.
