>>1417892That's not how it works. Drivetrains tend to skip after you change your chain, because the cogs are worn and the chain isn't. It's with a NEW chain that it will skip. Then you change your cassette. Then if it still skips you change your rings but good ones will last many a cassette.
If you just wait until it skips with a worn chain then definitely your chainrings will be fucked.
But if you change the chain when you're supposed to, and then it skips, you generally get away with just a new cassette.
All this stuff is cheap. You're being lazy not thrifty.
