What's the sweet spot for 11s cassettes and chains?

Maybe extend your chain-ring life for another 5k miles by switching out a chain sooner, but its not like we're talking mortgage payment sized money here. Just ride.

What ever works for you. Chainrings do not wear as fast so long as you don’t use a worn chain. I get far more that 10-12k miles out of mine. I can get that much life out of my cassettes. And chainrings on my bike cost more that $125 to replace. In fact, that’s about the cost for a single chainring. I’ll leave the math to you.
