KMC chains have been our favorites for a while. They play well with a wide range of drivetrain systems and last as long or longer than others for a reasonable price. This one has nickel coated outer plates and is a great long lasting chain for a wide rage of applications.
If you're using this for a recumbent, you'll need 3 and then you can trim to your current length. Crank forward bikes will require 2 chains.
