X12 Aurora Waxed Chain - 126 Links

The KMC X12 Aurora Waxed Chain delivers smooth shifting, long-lasting performance, and low-maintenance efficiency right out of the box. Treated with KMC’s factory-applied GO Waxed Formula, this 12-speed chain eliminates the need for at-home waxing and helps riders spend more time on the road or trail and less time cleaning and re-lubing.

Designed with Double X-Bridge shaping and precision chamfering, the X12 Aurora provides crisp, quick gear changes under load. The wax treatment resists dirt accumulation better than oil-based lubricants, keeping drivetrains cleaner and extending component life. A Titanium Nitride coating enhances durability, corrosion resistance, and overall chain smoothness for consistent performance in all conditions.

• Factory waxed for reduced maintenance and improved drivetrain longevity
• Double X-Bridge design ensures fast, precise shifting
• Chamfered inner and outer plates engage cassettes and chainrings smoothly
• Titanium Nitride coating provides high surface hardness and corrosion protection
• Cleaner operation with less dirt build-up compared to oil-based lubes

With 126 links and compatibility across 12-speed drivetrains, the KMC X12 Aurora Waxed Chain offers reliable, efficient performance for riders who value clean, quiet, and durable operation without the extra prep work.
