Inkesky 4 Pairs (2 Cards) Re-usable Quick Link for Bike Chains - Compatible with Shimano/KMC/Campagnolo/SRAM Inkesky Re-usable Quick Links for Bike Chains

Coating & Color Options:

Nickel Plated (Silver): This is a common plating. Nickel is an alloying metal primarily used for steel refinement. It enhances the steel's resistance to corrosion, increases its hardness and toughness, and provides effective rust protection.

Titanium Nitride Coating (Gold): This coating offers high hardness and corrosion resistance, providing better performance than Nickel Plating.

Titanium Nitride Coating (Rainbow): Similar to the Gold Coating, this option also features high hardness and corrosion resistance, outperforming Nickel Plating.

DLC Coating (Black): This Diamond-Like Coating (DLC) is extremely hard, reducing friction and ensuring smooth, optimum shifting behavior. Its performance exceeds that of Ti-N Coating and Nickel Plating.

Reusability: The SUMC chains are reusable for 3 to 5 times, ensuring longevity and cost-effectiveness.

Compatibility: These chains are compatible with Shimano, SRAM, Campagnolo, and KMC chains, making them a versatile choice.

Packaging: Each package includes 4 pairs of quick links (2 cards, each containing 2 pairs), providing a convenient solution for maintenance and repairs.

Customer Service: SUMC is confident in the quality of its chains and offers a free refund service within three months, ensuring customer satisfaction.

In summary, SUMC offers a range of coating and color options, including Nickel Plated (Silver), Titanium Nitride Coating (Gold and Rainbow), and DLC Coating (Black), all of which provide superior performance and protection compared to traditional Nickel Plating. The chains are reusable, highly compatible, and backed by a customer-friendly refund policy, making them a reliable choice for cyclists.
