#1 Who does this manually?

Bike maintenance tracking in three steps.

Connect Strava to sync bike rides

Connect Strava to sync bike rides

Connect your Strava account, and Geer syncs your bikes and rides automatically. Add your components, set maintenance intervals, and go ride without that guilty feeling of neglect.

Add bike components to track wear

Add bike components to track wear

Chain, cassette, brake pads — whatever. Set suggested service intervals and you're all set. It takes under 5 min.

Get bike maintenance alerts

Get bike maintenance alerts

When service time arrives, Geer sends you notifications that are harder to ignore than your bike's squeaking noises. Service, reset the counter, and earn back your bike's respect.

Built for cyclists who prefer riding over wrenching.

From component wear tracking to Strava sync — everything to keep your bike in top shape.

#5 Don't trust us

Don't take our word for it.

I used to track chain wear in a spreadsheet like an absolute psychopath. geer took over and honestly — my bikes have never run this well.

Marcel N.Road cyclist · 12.000 km/yr

My mechanic actually noticed. He asked what changed — my bikes were suddenly coming in to be serviced on time instead of half destroyed.

Anna B.Gravel cyclist · 5.000 km/yr

geer saved my Dura-Ace cassette. Chain was at 3,800 km and I would've ridden it another 2,000 easy. That one alert paid for it.

Frequently avoided questions

Geer is a progressive web app, meaning you won't find it in the App Store or Play Store. The great news? You can still enjoy Geer just like a native app — no need to open your browser every time or deal with annoying browser bars. Simply save Geer to your home screen, and voilà! It's ready to go, just like a native app. Enjoy the ride! 🚴✨

Here's how you install

No, Geer works seamlessly with any Strava account.
While Strava allows you to track your bike parts, it does have its limitations: it's desktop-only, doesn't provide maintenance suggestions, and won't notify you when a service is due. That's where Geer comes in! Our app works seamlessly on any device and offers all the features you need to keep your bike in top shape. 🚴🔧✨
#7 Ready?

Track it or trash it.

Your drivetrain is degrading right now. geer keeps count, so you don't have to guess.
