Know your bike, down to the individual component.
Every other bike maintenance app connects to Strava and stops there. Componentry connects to Strava, Wahoo, Garmin, and Hammerhead — and tracks every component's wear automatically, across every bike you own.

The first app serious cyclists install after Strava
Strava tracks rides. Componentry tracks what those rides do to your bike. Connect once, and every activity automatically updates the wear on your chain, cassette, brake pads, tyres, and electronic shifting battery — no manual logging, no guesswork, no spreadsheets.
The category has several good options, and this page compares them honestly. But every one of them stops at recording what your components have already done. None of them model what those components will do next — no watts lost, no personalised lifespan, no replacement date. That is the gap Componentry was built to close.
Every other app counts what you have ridden. Componentry models what comes next.
Distance tracking tells you a chain has done 3,000 kilometres. It does not tell you that the chain is costing you four watts right now, that your terrain and weather are wearing it faster than the manufacturer assumed, or roughly when it will run out. Componentry models all three.
Chain power loss, in watts
Componentry estimates the watts your chain drivetrain is losing and splits the figure three ways — contamination, lubrication state, and chain stretch — so you can see how much of it a clean and a re-lube gets back, and how much is genuine wear. The coefficients are anchored to published lab friction data from CeramicSpeed, Friction Facts, and SILCA.
A lifespan based on how you actually ride
Your terrain, intensity, weather exposure, descending, and riding volume over a rolling twelve weeks produce a lifespan for each component that differs from the number on the box. Two riders who log identical distance get different answers, because they should.
A replacement date, not just a percentage
Componentry projects the calendar date each component runs out, and simulates where every part on the bike will be on a target race day. When there is not enough riding history to answer honestly, it shows nothing rather than a number it cannot stand behind.
This is the part that is hard to copy. Personalised wear modelling runs on FIT-file data — the power, elevation, and session detail that Garmin, Wahoo, and Hammerhead record, and that a Strava activity feed does not carry. Every other dedicated maintenance app connects through Strava alone. The integrations are not a separate feature from the predictions; they are what makes the predictions possible.
Chain power loss works on every account, Strava-only riders included. Personalised wear predictions need a Garmin, Wahoo, or Hammerhead connected and around ten rides to calibrate — until then Componentry hides them rather than showing you an estimate it cannot support.
ProBikeGarage
The largest dedicated maintenance tracker — ProBikeGarage states 160,000+ cyclists. Native apps, web app, and solid core tracking. Connects through Strava only, and does not track electronic shifting batteries.
See the full comparisonStrava
Now tracks individual components with per-component distance — managed on the web, with no maintenance alerts for bike parts, no service history, and no component swaps. A starting point, not a maintenance tool.
See the full comparisonGeer
Clean design, privacy-first, and aggressively priced at €20/year. A PWA — not in the App Store or Play Store. Strava only, with Wahoo and Garmin still on the roadmap. No electronic shifting tracking.
See the full comparisonWatchMy.Bike
Component tracking with public bike profiles, cost analytics, and document storage. Web only — no native apps — and Strava is the only way rides get in.
See the full comparisonVelo Buddy
Native iOS and Android apps, and the only other app here attempting wear prediction — though the AI and watt-loss claims are not substantiated anywhere public. Ride ingestion is Strava and Ride with GPS only, there is no web app, and at $4.99/month it is the priciest dedicated option.
See the full comparisonMainTrack
Free, with no bike or component limits, and quietly maintained by one developer since 2019. Excellent component-assignment tracking. iOS only — no Android or web — and Strava is the only ride source.
See the full comparisonBikerly
The simplest way in — a free, browser-based maintenance log, with Pro at £4.99 once. Nothing to install, and nothing in the category costs less. Strava is the only ride source, there are no native apps, and automatic service alerts are still a planned feature.

Every dedicated maintenance app takes its ride data from Strava. ProBikeGarage, Geer, WatchMy.Bike, MainTrack, and Bikerly connect through Strava alone; Velo Buddy adds only Ride with GPS. For cyclists whose rides land in Garmin Connect, Wahoo Fitness, or Hammerhead's platform first, that means an extra sync step, sync latency, and another point of failure.
Componentry connects directly to Strava, Wahoo, Garmin, and Hammerhead. Your rides sync in real time, and your component wear is calculated from the right source. Stop guessing whether the sync worked.

Sync automatically from Strava, Garmin, Hammerhead, and Wahoo.
Your Di2 or AXS battery doesn't care about your training schedule.
Electronic shifting is standard on performance bikes at every price point, yet not one competitor tracks electronic shifting battery health — not ProBikeGarage, not Geer, not WatchMy.Bike, not Velo Buddy, not MainTrack, not Bikerly. Componentry monitors your Di2, AXS, or EPS battery alongside your mechanical components. Know before it dies mid-ride.
