Many riders never actually service their suspension at all. This is a shame; it’s like buying a Ferrari and never changing the oil. Eventually, your nice bike rides poorly, and the money you initially invested into suspension is no longer returning its benefits. And the degradation has happened so slowly you probably haven’t noticed it, so you shrug and decide you don’t need to do anything, anyway. But every time you ride your bike, suspension oils continue to break down, seals continue to wear out, and the potential for a mid-ride problem starts to increase.
