SRAM PC 870, and KMC Z72. Both were under 2500 kilometers. Z72 lasting only about 3-4 months, while SRAM lasted 5-6 months. I do between 300-500 kilometers per month.
Next up will be KMC X8.
Cassettes are changed regularly, but even when new, chains don't last long.
Chainrings are steel and look OK (no shark teeth), but I'm considering changing them just in case... though they look OK after some 3 and a half years and some 15,000 kilometers.
