SRAM POWERLINK 9 SPEED  (2 PAIRS) AS SHOWN

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.

NB: One link comprises of the two halves and is sufficient to connect one chain.

POWERLOCK, they fit together but then are not designed to come apart again.

WILL FIT PC951,PC971,PC991 CHAINS
