Drivetrain tracks every component on every bike, pulls your ride mileage straight from Apple Health, and warns you before a $30 chain takes $250 of drivetrain with it.
Every cyclist knows it. Almost nobody tracks it well. Spreadsheets get abandoned, Strava doesn't care about your components, and the bike shop only finds out when it's too late.
"I cooked a $200 cassette by ignoring a worn chain. I built Drivetrain so it never happens again — to me, or to you."— the cyclist who built this
Precision tracking that runs quietly in the background — so you only think about it when something needs attention.
Reads your cycling workouts and attributes the miles to the right bike automatically. You ride — it counts.
Every component shows live wear against its interval. One glance tells you what's fine and what's about to bite.
Get notified at 90% and 100% wear — capped at one alert per part per week, so it warns without nagging.
Record every job with date, parts touched, cost, notes and photos. Replacing a part logs the service automatically.
Your top three parts needing attention, right on your Home Screen — across every bike in your stable.
All local, all private, no account required. Your garage syncs across iPhone and iPad over CloudKit — for free.
Every bike, every part, every mile — tracked automatically and color-coded so you always know what's next.
Your whole garage, ranked by what needs attention.
Each part gets a live wear ring and miles remaining.
Drill into a bike to see every component, sorted by wear.
Three minutes of setup, then it works on its own for the life of the bike.
Road, gravel, MTB, commuter — each with its own components, install dates and wear intervals you can tune.
Drivetrain pulls in every cycling workout and adds the miles to your active bike. No app to open mid-ride.
When a part crosses the line, you'll know. Hit "Replace," and the service log and mileage reset themselves.
Start free. Go Pro when your garage grows.
