Garmin quietly releases a key feature that could save you money on replacement parts

Garmin has switched on a feature it barely shouted about: Gear Tracking, part of the June 2026 software update for its Edge cycling computers. It lets you set an expected lifespan for each component on your bike, then automatically tallies the distance you ride on it and warns you as it nears the end of that life.

You can log individual parts - chain, cassette, chainrings, tyres, wheels - or whole sets like a drivetrain, and even your shoe cleats. The update is free and rolling out gradually via automatic device updates, Garmin Express or the Garmin Connect app.

Here's the mechanic's logic Garmin is leaning on. A chain stretches as it wears, and a stretched chain starts chewing the teeth on your cassette and chainrings - the much pricier parts of a modern 12- or 13-speed drivetrain. Swap the chain in time and you usually save the cassette.

The workshop rule of thumb: replace an 11- or 12-speed chain at 0.5% wear (0.75% on 8/9/10-speed); leave it past 1% and you'll almost certainly need a new cassette too. In distance terms, a chain typically lasts 2,000-3,000 km, stretching to 5,000-6,000 km with dry weather and regular cleaning, while a cassette runs roughly 6,000-8,000 km.

Setup happens in Garmin Connect first: add each component (type, brand, expected lifespan) in the app or on the web, then assign it to your bike. From there the Edge logs distance to it on every recorded ride and shows wear progress bars on the unit. One limitation worth knowing - there's no retroactive mileage import, so parts already in use start from zero.

The rollout itself has been messy. On Garmin's forums, Edge 1050 owners reported struggling to even find the feature after Garmin emailed to promote it, and dedicated maintenance apps flag a longer-term snag: the wear history lives inside Garmin Connect, so it doesn't travel with the bike if you sell it.
