Dialled MTB keeps your mountain bike running right — without the spreadsheet, the guesswork, or the ride you cut short because something needed attention three weeks ago. TRACK MAINTENANCE BY REAL RIDE HOURS Service intervals based on how much you actually ride, not the calendar. Log a ride and your fork, shock, drivetrain and brake intervals move with it. See what's due and what's overdue the moment you open the app, and get a reminder before it becomes a problem on the trail. DIAL IN YOUR SUSPENSION SETUP A setup calculator built around your bike and your riding style — fork and shock pressure, sag, and tire pressure, saved per bike. Every value shows how confident it is: confirmed by you, estimated, or suggested. Change a tire or a casing and the numbers follow. CONNECT STRAVA AND APPLE HEALTH Link Strava and your rides import automatically, assigned to the right bike through gear linking. Or connect Apple Health for on-device import of your cycling workouts. Either way, your service intervals stay current without you logging a thing. ASK THE ADVISOR Practical setup and maintenance guidance from an AI advisor that already knows your bike — its travel, its current setup, its service history, the tires on it. Get a suspension recommendation and apply it to your saved setup with one tap. MORE THAN ONE BIKE Trail bike, enduro rig, hardtail, gravel bike. Each one gets its own setup, its own service history, its own intervals. BUILT TO BE USED IN A PARKING LOT Works offline. Log a ride or a service with no signal and it syncs when you're back.
