Strava already has the feature you crave. (are you on commission?)
There’s no need to look at what rides that bike has done though. if you really want to know EXACTLY what rides the bike has done simply look through your activity feed
in your profile, all your bikes are listed, simply click on the bike and add a component (in your case “Fork”) Strava will automatically log the mileage of the component, You can either add a new fork each time you serviced it or use the notes section to keep track of maintenance dates/mileage.
How many bikes do you have and how little riding do you do if you can’t remember roughly how much you’ve ridden them? the service intervals are only a guide you know.. if you only commute in the dry you won’t need to service your fork as often as if you mainly ride off-road in the wet.. even with a crappy Fox product.
