Regular servicing or wait until there’s an issue?
This had waited a little too long, but luckily there was no damage. Now they’re running smoothly again and protected against water and dirt.
The hard question – when should it be done again?
The easy answer – it depends! Weather, mileage, conditions, general maintenance can all affect the interval.
If your wheels don’t spin well, wobble on the axle or sound/feel grindy get in contact to arrange a service. If they don’t, when WAS the last time they had some TLC…?
