I'm looking to get other riders experiences with how often cassettes and chainrings usually have to be replaced per the number of chain replacements. On my 2 road bikes I usually find roughly the following:

1 cassette replacement per 3 or 4 chains

1 chainring set (both inner and outer) replacement per 5 or 6 chains

Is this is about what would be typically expected?

P.S. Yes, I understand cassettes and chainrings should be inspected for wear rather than replaced based on the corresponding number of chains. Of course I check cassettes and chainrings for wear before replacement, but I'm still curious as to how often other riders are replacing cassettes and chainrings in comparison to chains.

    Your numbers are about what I'd guess, from my experience. I wouldn't expect to get much more precise.

  • For my road bike a cassette is roughly 1.25 times the cost of a chain. I tend to wear them both out and replace both at once. Get about 3000-5000 km off them, though shifting can get a little sketchy at the end.

  • On my road bike, I get 8,000 to 15,000 km to a Dura-Ace chain. A cassette lasts 3 or 4 chains. I just about never wear out the chainrings on my bikes before selling them. I do 20,000-30,000 km a year and sell my bike after riding it for 2-4 years.

    I'm voting to close this question as off-topic because it is a survey, not a question.
