A customer dropped off the rear wheel from their のむラボホイール5号 (Nomu Lab Wheel No. 5).
It's a PowerTap hub, and they said the bearings seemed to be going bad and asked me to take a look.
As I always mention, generally when a customer notices symptoms, the problem is often way past "something's a little off" and into "too late to fix" territory.
But this time it wasn't quite like that.
When I took it apart and inspected it, there was just a slight roughness in the rotation of the bearing on the non-drive side.
But it was so subtle—I was actually impressed they'd noticed it at all.
At this level, I'd normally just top up the grease, but the customer wanted the bearings replaced, so I went ahead and did that.
Wait a second. While I'm at it.
