I bought a used Trek 2500 Alpha SL a couple years ago and have since put about 1,500 miles on it. I clean the chain with ProLink lube, but the chain is still a bit rusty, but seems to work fine..Is there a recommended number of miles you should get out of a chain?
I found a good answer:
The rule of thumb is you should replace your chain BEFORE a foot of chain has stretched to the point where it is a foot and one eight of an inch.
Checking this is Simple:
You may get anywhere from 2000 miles to 20,000 miles on a bike chain before it needs replacement. It all depends on how much grit and dirt accumulate on the chain and your style of pedaling.
Hi Tom -
I just published an article by Lennard Zinn at VeloNews about this subject.
Check it out:
It pretty much says the same thing as the answer you found, but offers some tools to help you get the measuring job done.
