A bicycle drivetrain is a costly investment. If you don’t replace a $30–$40 chain in time, it will «eat» your cassette and chainrings, multiplying your repair costs. Usually, we check for wear with a chain gauge or try to guess: «How long has it been? A thousand kilometers or three?»

In BikeNote, I solved this problem with the «Garage» section.

How it works

You don’t need to keep a separate notebook or calculate the mileage of every part in your head. The principle is simple:

• Set a tracking limit: for example, 2,000 km for a chain (this is the default in BikeNote, but you can change it).
• Upload your tracks: every new GPX file subtracts kilometers from the set limit (the progress bar decreases).
• See your progress: the app automatically sums up the distance of all rides and shows a clear visual indicator of wear.

What if the part isn’t new?

If you started using BikeNote when your chain had already covered 500 km, there is a «Resource» field in the settings. You simply enter the remaining limit you want to track, and the countdown starts from that value.

More than just a chain

In the BikeNote code, I’ve included base limits for essential components:

• Cassette: 6,000 km
• Tires: 4,000 km
• Fork (Service): 1,500 km

These aren’t just numbers — they are your maintenance roadmap. As soon as the progress bar turns red, you’ll know exactly when it’s time to visit the workshop.

Total Flexibility

All limits can be adjusted to fit your needs. For instance, if you ride a road or gravel bike, fork service might not interest you at all. In that case, you can rename that scale to «Brake Pads» and track their wear instead.

Furthermore, you can rename every item in your garage. Instead of a generic «Chain,» you can specify your exact model, like «KMC X11», making your tracking even more precise.

Why upgrade to Pro?

In the free version of BikeNote, you can view general statistics, but full Garage management — setting custom limits for specific components and tracking individual wear for every part — is available in the Pro version.

This is the exact feature that pays for itself in a single season: you simply stop wearing down your drivetrain until it becomes scrap metal.
