Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

will a chain suffice?

I have about 2,000 miles on a bike with ultegra 10. It runs just fine, but the drivetrain is getting a little noisy. Will I be ok just replacing the chain, or will I have to get a new cassette too?

What makes you think the chain is bad? I'm not saying it isn't but i dont think you can just assume that drivetrain noise is strictly a chain problem.

Is everything lubed? Is the derailer tuned up right?

In either case i highly doubt you need a new cassette.

all of hte maintenance stuff I read says that one should replace the chain 1x/year, and I am repidly approaching that point.

IMO 2000 miles on a chain is nothing. Just clean and lube it all and you'll be fine.

Clean the chain as mentioned. But also check the derailler adjustments - your cables can certainly stretch over a year to the point where you might hear some rubbing.

Just get a new chain and save your time chasing the noise around from component to component...
I've had various noises on the drivetrain for over a month. I tried just about everything (servicing derailleur, adjusting all screws, lots of lube) and in the end, all I needed was a new chain. I'd estimate 3000 miles on the chain.
The cassette would only need to be changed if sufficiently warn. This should take a while unless you're riding upwards of 15 hours a week. Either parktool or Sheldon has a good photo or explanation...

+1. Unless you've really been abusing the bike, your chain and cassette are both fine. If you haven't adjusted your derailleur in the past year, it is almost certainly out of adjustment. If you put install a new chain or other components and the problem is your derailleur, you'll still have the noise. No sense in throwing parts at a problem until you know it's necessary.

Like Machka says, 2,000 miles is nothing.

If you're a big guy and you sprint a lot or climb a lot 2000 miles might be close to time for a new chain. There are tools to measure chain stretch. If you ride in the wet you will also go through drivetrains quicker.

Use your cable adjusters to fine tune any cable stretch. If you have not been playing with the adjustments on the FD or RD and it was not noisy before it very well could be your chain.

One clean freak I know cleans his bike and chain about every ride. The problem is he has no compressor to blow the degreaser out of the chain and lubes his chain right after cleaning it. So…the lube is corrupted by the degreaser and he ends up riding a dry chain. I told him to leave the bike in the sun and let the chain dry out till the next day or the next ride and lube then. During the winter lean it by a heat vent so it blows on the chain. His bike is a lot quieter now.

Also 10 speed chains are really changing how we need to maintain them. All the advice you have gotten here is correct for certain chains. As we have moved from 5 to 6,7,8,9 and now 10 the Maintenance requirements have changed. As an old wrench I see more issue with the move from 9 to 10. I know I will get heat here but the best thing is to toss a 10 chain every 1500. I have found too many that measure Okay at over 1500 on about 98% of the links but the other 2% are too much and those are the ones that will blow. Also installing a 10 chain is almost an art form. If you bend it sideways to check the install rivet you just killed the chain. People that have changed their own chains for years are now having problems with their 10’s. They are just dang delicate.

9 and lower spec chains you can manhandle and push much further than a 10.
