    Yes, you most definitely need a new chain with that kind of mileage. You probably need a new cassette too if you haven't changed it in that time. If you recently changed the cassette but not the chain, that is definitely a reciepe for chain slippage. Get a new chain for sure.

    Measure 24 half-links of chain. If the length exceeds 12-1/16" (highly probable), you need a new chain. If it exceeds 12-3/16" or so, you may need new cogs, as well, and even a new chainring or two. I would start with just the chain and see how it goes.

    If a new chain and cassette don't help, check your rear derailleur hanger alignment.

    Does the same logic and measurements apply to a Campy chain vs Shimano? Also the same for 9 and 10 speed chains?

    Ya gotta measure to determine if a replacement chain is needed. Mileage doesn't mean anything.

    True.

    I've found a chain lasts about 2500-3000 miles. Usually wears faster if it isn't kept clean and lubed. After that, it gets too worn and starts damaging the cassette and even the chainrings.

    Yes, that applies to any brand of chain and for any number of cogs on the rear.

    You probably need a new chain but there could be other causes for the symptoms like a stretched shift cable that simply needs adjustment.

    I have that problem also but only in 2nd& 3rd gear. it feels like the derailler is out of whack. it shifts fine and then a few rotations later it will try to go into 3rd or 4th but only when Im cranking down for climbs. as soon as I let off the torque it does fine. I have another cassette that I can install but it is old although not worn out and I am not sure if that is the problem. I have installed another cable and same problem. I had the entire drivetrain on another bike with no problems. I switched the entire drivetrain and nothing but problems. could it be the chain being too short? I did break a link and had to take another off

    Does your bike have a replaceable rear derailleur hanger? What kind of bike and component group are you talking about. Did you ever check the alignmet of the rear derailleur hanger with the special tool?

    You broke a link and had to take off another? You mean you broke a chain while riding?

    thank you for telling me what I left off in order to get an answer. yes it does have a replaceable hanger. it is deore der.,bb,and crank. it is a Shimano chain on an 01 Diamondback XTS3. I was not aware of a tool to check the hanger. I did break the chain while riding. sounded like a gun as I was climbing a hill and painfully hit my lower region as I crashed. the bike has had some crashes so I am not sure of the alignment of the hanger. the bike the components were on before was a Mongoose XR8500
