SC-25

The SIGMA PRO connector makes chain assembly quicker and easier, and tool free. The pinhead groove interlocks with the top plate securely making it as strong as the other links in the chain, and keeping shifting sweet. The pin on the connector has the same TAYA Diamond Hard Technology treatment as every other link on the DHT chain range providing self-lubrication and extreme durability. The millions of Sigma Pro Connectors in use around the world have demonstrated its reliability for over 25 years.

Pass the pins of the Sigma Pro link through the ends of the chain.

Place the Sigma top plate over one of the pins and push the plate into the groove.

Bend the chain to allow you to fit the second pin into the plate until you hear a click. Check the chain is linked correctly.

No-Tool Required

TAYA’s patented design revolutionizes chain installation requiring no tools to fit. The unique configuration provides security, strength and durability.
