Default Cassette change?

I am easy on drive-train's. I get 6000 miles on chains without going over the limit on 11 speed shimano. My question is right now my cassette a 11-28 has some 16000 miles on it and works fine. No Skipping I am getting ready to put a new chain on pretty soon maybe another 1000 miles. Should I go ahead and swap out the cassette. My instincts tell me to just keep riding. If for some reason a new chain causes a skip then yes i need new cassette. The bike is Ultegra 6800 and shifts like a dream. I put a new cable on the rear today and was thinking maybe just order up a not only the chain but a new cassette. Cassette are a mystery on wear for sure.

What do all the minds in here think? It is not broke leave alone or just go new and be done for hopefully anther 16000 miles, not kilometres.

Change the chain before it shows symptoms. Change the cassette after it
shows symptoms (i.e. chain skipping).

Does anyone here know a downside to running a worn cassette BESIDES
chain skipping?

I'd say try the old cassette, but be ready to change it. I strongly
suspect the chain will skip. Please report back.

I don't have any data, but I'd bet that the chain will wear much more
quickly. I think the load will be more concentrated on one link at a
time, instead of shared between several chain links.

Good question. Damn good question.

I would say it's already too late and ride it out and then change
everything. I'd have changed the chain at 2,000 miles, but that ain't
the question :-)

For me I really don’t think it will skip on a new chain. I live in flatlands Illinois and keep my chain clean. I have quick link and will remove and dunk at 500-750 mile intervals. I am not a masher. I guess I may go ahead order a new chain and cassette.

You seem to put on enough miles, having a cassette in reserve seems
reasonable. What brand of chain? I'm told some last a LOT longer than
others.

I *may* have got 6k on a Campy chain once, a chain I cleaned
obsessively, but I really don't remember the number. I've changed to
frequently-changed KMC's now.

I have all Shimano drive train. I buy the 701 directional chains and either Ultegra or 105 cassettes. I think all Shimano shifts better. I have all 6800 equipped bike. I personally believe all Shimano gets best most precise shifting. Mine shifts perfect never misses until cable wears out. Then it is always cable head gets frayed.

Yes, riding out of the saddle. Could be very much 'down'.

Since there's no definitive way to know about sprocket wear,
change your chain and don't stand up for the test ride
afterwards.

I believe that there is data to show that worn cassettes or chain
rings accelerate chain wear.

Experience tells me your new chain will skip when installed. Whether you
want to wait to find out is up to you. I’ve never done 6000 km on a chain,
much less 6000 miles. Any time I’ve tried to exceed the chain limits I’ve
toasted the cassette.
