Keep using Strava — everyone on this page does. Its built-in gear tracking is enough if you only want a passive odometer on your bike and components. Add Componentry when you want the maintenance layer: alerts before parts fail, service history, component swaps, battery tracking, and wear that reflects how you actually ride.
Strava's gear tracking is free, already on your phone, and better than it used to be: you can add individual components — brand, model, weight, install date — and each accumulates distance automatically from your rides. As a passive component odometer for a cyclist who wants zero extra apps, it's a reasonable starting point.
Strava counts kilometres against a component. Componentry models what those kilometres cost: the watts your drivetrain is losing right now, split into contamination, lubrication state, and chain stretch; a lifespan weighted by your terrain, weather, and intensity rather than a manufacturer's average; and the calendar date each part runs out. Strava's gear feature has no concept of any of it — and, connecting only to itself, no way to acquire one.
Strava's components accumulate distance — and that's the whole feature. There are no maintenance alerts for bike components, no service intervals, and component management lives on the website only, not in the app. Componentry turns the same rides into service thresholds, alerts before failure, and a maintenance plan per component.
Strava counts kilometres; it treats all of them the same. Componentry calculates wear across distance, moving time, and elapsed duration, and enriches each activity with weather data. The same chain wears differently on a rainy commute than on a dry Sunday ride — your estimates should know that.
Strava has no concept of a Di2, AXS, or EPS battery. Componentry tracks electronic shifting battery health alongside mechanical components and reminds you to charge based on your riding patterns. Know before it dies.
Move your race wheels to the training bike? Swap a cassette? Strava components are pinned to one bike and a retired component can never be un-retired. Componentry tracks every transfer — when it was installed, on which bike, and total wear accumulated across all of them — plus full service history with notes.
Strava only counts mileage recorded on Strava. Componentry connects directly to Strava, Wahoo, Garmin, and Hammerhead, so your component wear is calculated from wherever your rides actually land — in real time.

Strava's gear tracking is free, and its $11.99/month subscription is priced around training and social features — not maintenance. Componentry at $4.00/month is the purpose-built maintenance layer Strava never built, and it works on top of your existing Strava account, not instead of it.
There is no data lock-in to fight. Connect your Strava, Wahoo, Garmin, or Hammerhead account, add your bikes, and log each component once with its current mileage. From that point every ride updates your components automatically — nothing to migrate, nothing to maintain by hand.
Connect your Strava account in 60 seconds. Zero manual logging from day one.
