Intervals.icu does gear tracking now:
Just found this, looking for a way to track mileage on a chain - I knew the TR forum would have an answer! This seems to be the best of the options for me, great stuff!

Alerts can be interval or target and based on mileage. Limited to chain, tires, cables, shocks and brakes.
Not just for you, @splash, but I think probably a really useful partner tool for anyone trying to track usage:
Activity Fix doesn’t get enough attention in this world. It’s an IFTTT tool for Strava’s API that can do loads of things, but the most relevant usage here is the ability to have it automatically change which bike is selected based on a particular Ant+ ID in the upload. So you can make it so any time a strava upload includes a particular Ant+ sensor (power meter, Di2/AXS, cadence sensor, etc.) it will automatically edit the strava activity to select the appropriate bike.
A @GPLama video introduced me to it years ago and I’m always surprised more peope aren’t using it.
There’s a lot of factors that impact wear beyond just time/mileage though. I also have a bunch of different bikes, wheels, chains, cassettes, tyres, etc. But the reason for having all that different gear is because it gets used in different conditions and that means it wears at different rates. I chew through chains on my winter bike a lot quicker than on my race bike, because that bike goes out in the wet, goes out in winter when there’s salt on the roads, I tend to run cheaper chains on it as a result, I sometimes use thicker lubes which increase wear but decrease maintenance, etc. Tracking the mileage I get on that chain vs on the chain on my race bike which only gets waxed, rarely gets wet, doesn’t go anywhere near salted roads, and will be meticulously cleaned and re-waxed if it does get dirty is certainly interesting, but not particularly useful at telling me when I need to change my chain when I can just check that in 10 seconds with a chain wear tool.
Haven’t read all the post in this thread, but I’m an old curmudgeon Luddite and have made up Excel spreadsheets for this purpose forever, for cycling and many other things. It’d probably be better to do it as a database in something like Microsoft Access, but Excel is simple and works well enough for my purposes.
