SRAM Powerlink Gold Chain CONNECTOR
Every chain is only as strong as its weakest link - traditionally, the connecting link. In contrast, the PowerLink™ connection is just as strong and durable as every other link in the chain. It can be opened and closed as may times as you want without using any tools.
PowerLink means no weak links.
NOTE Pair means a pair like a pair of shoes, a pair of links means one complete link (2 sides)
IMPORTANT: 10SP Links are POWERLOCK, they fit together but then are not designed to come apart again.
