YBN MK12E Flat-Top 12-Speed E-Bike Chain 136L (Ti-Rainbow)

YBN's MK12E is a solid pin-and-plate flat-top chain built for the higher torque and wear that mid-drive e-bikes put through a drivetrain, while also working fine on a standard 12-speed road, gravel or MTB build. It uses DHA chromium carbide-treated pins and rollers plus a hard chromising treatment for a tensile strength of 1200kgf, and still shifts smoothly and quietly on Shimano, SRAM and other 12-speed derailleur drivetrains.

This Ti-Rainbow version has an oil-slick, titanium multicolour finish over the same flat-top construction.
