Just curious, I tried to find this by searching but with no luck. Is there a way to inspect bearings without removing the wheels? It looks like there may or may not be a removable cap on the plastic portion of wheel center (with BCB logo). I’m just wondering for future reference. I understand the BCB stance on not using grease gun, etc, I’m just wondering for intermittent inspections if there is a cap or whether need to remove entire wheel just to see if there are any leaks, etc.
