Product details
Product details
KMC X12 Waxed 126L
The KMC X12 Waxed is a chain for 12-speed drivetrains based on the Shimano standard, including the Shimano, Campagnolo, and TRP applications specified by the manufacturer. This version is supplied with 126 links and a nickel-plated silver/black finish. Selection requires verifying the drivetrain standard, not just the number of speeds: this model is not compatible with SRAM systems.
Double X-Bridge technology and waxed version
The Double X-Bridge technology is KMC's solution designed to improve shifting. The Waxed version is wax-treated and stands out for its two-tone nickel-plated silver/black finish. The manufacturer's code BX12NB126W1 identifies this configuration, distinguishing it from the Silver variant and the other versions in the X12 range.
Length and supplied assembly components
The package includes a MissingLink quick link for chain closure. The stated size is 1/2" x 11/128", with 5.2 mm pins. Weight should be assessed against the reference length used by KMC: the stated 236 g refers to 110 links, while the chain is supplied in a 126-link length.
