Sram PC-991 Chain with Powerlink Gold 2012
Delivering light weight, strength and smoothness to your drivetrain. BlackBox racers know - SRAM PowerChain is designed to stand up to the toughest courses and competitors. From the convenient PowerLink connectors that eliminate the need for tools to the GLEITMO lube that protects against dirt and friction, these chains set the standard for durability and reliability.
SRAM's extremely strong and precise chain technology. The PowerChain II is optimized for increased front and load shifting performance while retaining excellent rear shifting precision. The Step2 riveting process increases the Push Pin Power to provide increased strength and durability.
This has been a great chain that I have been using for the past few years and it's still running on my bike after over 1000 mountain biking miles. Powerlink is fantastic as well, something that Shimano chains don't have.
