KMC X-FlatW Waxed Chain – SRAM Flat-Top 12/13-Speed – Black

The KMC X-FlatW is a high-performance, factory-waxed chain developed specifically for SRAM 12 and 13-speed drivetrains that use Flat-Top chains. Its distinctive flat-top profile and KMC X-Bridge plate design support fast, accurate and stable shifting across road, gravel and mountain bike applications.

Pre-treated with KMC GO Wax, the X-FlatW delivers a clean, low-friction drivetrain straight out of the box. The wax-based treatment helps resist dirt and debris, reducing abrasive contamination and supporting longer chain and drivetrain life with less mess than a conventional wet lubricant.

The chain is supplied with 126 links and a black KMC CL550F MissingLink for straightforward installation.
