How many km to replace cassette and chain

Quoted message said:

I have all 105 groupset on my bike.
replaced chain with an ultegra chain at 4,000
nearly up to 8,000km.
Should i be replacing my chain and cassette at 8,000km?

NOT my front chain rings that have only done 6,000km?

Will i just push on until it slips, or will that kill the front chain
rings?

I am guessing this chain is still better than my old dirty greasy
crappy MTB chain. Can i put this Ultegra 10spd chain on a Trek 4300??

Besides the measuring of the chain for wear, riders need to keep the
chain clean and well lubricated.

I just replaced my entire drive train on one bike, going from a triple
chainring to a compact double chainring setup. But the old chain and
cassette had over 20,000 km of use, and I was only beginning to notice
slow shifting (no skipping yet). My other bike is at 12,000 km on the
original chain and cassette (but may be due for replacement soon).

I ride nearly every day, and alternate more or less equally between two
bikes. I try to clean each bike on about a two week interval. When I
clean the bike, I lube the chain with Pedro's Ice Wax, a wax-based lube
that, when I use it regularly, seems to keep the chain pretty clean (a
paper towel I use to rub off the excess gets a gray color, not black).

In 9 speed, I replace these rooms, on average:
- chain, every 5.000 KM
- cassette, every 3 chains, is 15.000 Km.

But, if mountain, the cassette make only 2 chains, that is 10.000 Km

Ignore the mileage. *Measure* the wear; it's not hard, and it tells
you directly whether you need to replace the chain. No guesswork, no
approximations.

This is fine for measuring chain wear, but to know when to replace a
cassette, I know of no better measurement than to replace the chain. If
the new chain skips, replace the cassette (or, at least replace the
offending sprocket).

Chainrings are less susceptible to such wear, but eventually will wear
out as well. I replace them when the teeth get too shark-toothed in
profile, or when they become too thin and begin to break off.

Sometimes front sprockets with worn teeth will exhibit chain suck. If
money is tight or replacement impractical for other reasons, a little
work with a file to remove side burrs and straighten out hooking on
the sprocket teeth will often restore the usefulness of the worn
sprocket enough to allow delaying its replacement.
