Just courious, I know the best methode is to measure the stretch, but just courious on average how many mile everyone is getting from chains?

I have been getting about 3000 miles from my campy 10spd chains without the permalink. My first campy chain went 4500 miles (too long) until I had to replace the chain and cassette. The next one lasted 2800 miles. My current one has only 1000 miles and going strong.....

I've got more than 8000 miles on a 9-speed Dura-Ace chain and it still measures just like a new one. But I weigh 165 and I'm not a big gear masher. This chain has never been removed from the bike. I clean and lube it often.

I managed to get 15,000 miles on my Dura Ace 9-speed chain before I replaced it. Like you, I never removed the chain and cleaned an lubed after every ride. However 15,000 miles is really pushing it.

The new bike has a new Campy 10-speed chain, I'll replace it at 3,000 miles. So far around 1,500 miles and no problems.

I don't use mileage. I use my Park Chain Checker. When it telle me my chain is worn, I replace it!
I don't keep mileage n veg

where are people getting these numbers from? Are they estimates or do you have mileage counters?

I change 'em out every 2-2.5K miles. I'm sure I could get more miles than that but chains are relatively cheap and I don't feel like worrying about whether or not my chain is going to fail me.

Its better to measure your chain. Stretching can be induced by worn gears. When a 12" section is streched over 1/8" I chuck it.
No such thing as averageKerry

Are you doing a lot of climbing? Are you a masher? How much do you weigh? How well do you maintain the drive train? What brand and model chain do you use? What kind of lube do you use? Do you ride in the rain a lot? Is it pretty dusty where you live? These factors have a huge impact on chain life. With Campy Record-9 chains on Campy steel (Chorus) cassettes, I get 10-12K miles (mostly flat roads, 90-100 rpm, ProLink lube, weekly re-lube, minimal rain riding, not much dust, worn out = 1/16" elongation per foot). With a Sachs R-99 chain, about 75% of that mileage. Lots of people seem to replace their chains at 2-3K. How would you average these figures?
6K miles for 1/16" stretch with C10 chain and Prolink .... nmJohnG

I use 2 chains and rotate them, about 10,000 miles for both.(nm)James

There is no reason to rotate a chain. Don't wast your time dude.
