A bike maintenance tracker monitors component wear across your rides and alerts you before parts fail. We compared the best apps for Strava sync, notifications, platform support, and pricing — so you don't have to.
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.
My mechanic actually noticed. He asked what changed — my bikes were suddenly coming in to be serviced on time instead of half destroyed.
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.
