It's not planned obsolescence, it's wear and tear. If my bike's groupset (chainring, chain and cassette) starts making awful noises and misses shifts after 50,000 miles of hard riding in all sorts of weather does that mean the bike needs to be thrown away? No, it just means that some parts have worn out and needs replacing.
