KMC X12
Best durable drivetrain upgrade for riders in wet or coastal climates.
This is the workhorse upgrade for riders tired of premature drivetrain wear. Its specialized anti-corrosion coating keeps things running smoothly through the worst weather, while the clever non-directional design makes installation a breeze. You sacrifice a bit of weight for the kind of durability that actually survives a full season of hard riding.
