A pair of Quick Link Connectors allows you to easily open and rejoin KMC chain without the need for tools. Choose either X9 or X10 depending on whether your chain is nine speed or ten speed. One pair is included in the purchase of Bulk KMC X9 Chain and in purchases of Bulk KMC X10 Chain. These Quick Link Connectors are sold as replacements or spares and are compatible with Shimano, SRAM and Campy.
Each year I buy a new chain for my recumbent because the prices are great here and the part lasts the 4-5k miles I ride between changes
KMC Quick link
This product is extremely well engineered and produced. It works as expected.
They work smoothly and easily, at least when new and clean. I made and broke the chain multiple times while adjusting length.
no issue....needed them for bulk chain purchased
Quick delivery and holds up well.
