The KMC X12 Blacktech Pre-Waxed Chain 126L Chain is engineered for cyclists seeking unparalleled performance and durability. Treated with the innovative KMC GO CHAIN WAX, this premium chain offers exceptional resistance to dirt and wear, ensuring a longer drivetrain lifespan and reduced maintenance. Its unique wax formula forms a protective barrier that lasts longer than traditional oil-based lubricants, making your rides smoother and your cleaning intervals less frequent.
Designed with precision, the KMC X-Series chains perfectly complement Shimano, SRAM, and Campagnolo systems. Featuring the advanced X-Bridge technology with precisely chamfered plates, this chain guarantees flawless shifting and consistent power transfer in every riding condition. Trusted by elite professional cyclists, the X12 Blacktech combines cutting-edge technology with a sleek, durable black finish that resists rust and maintains its striking appearance over time.
With its double X-Bridge design and non-directional build, this chain offers versatility and reliability for all 12-speed drivetrains (except SRAM Eagle Transmission T-Type and certain road/gravel models). The BlackTech surface treatment ensures the color is embedded into the material, not just coated, providing both aesthetic appeal and exceptional corrosion resistance. Included missing links make installation straightforward and convenient.
How often should I care for my KMC X12 Blacktech chain?
KMC recommends caring for your waxed chain after every 250 km on road bikes, or at least once a month. For mountain biking, cyclocross, and frequent riding in all weather, care should be done every 100 km.
Do I need to remove old wax before rewaxing the chain?
No, the chain does not need to be dewaxed before applying a new layer of KMC GO Wax. Simply ensure the chain is dry before application and follow the rewaxing steps for best results.
Is the black color on the chain a coating?
The BlackTech treatment is not a simple coating but a surface treatment that integrates the color into the material itself, ensuring a permanent and highly rust-resistant black finish.
Can I use this chain on any 12-speed drivetrain?
This chain is compatible with all 12-speed drivetrains except for SRAM Eagle Transmission T-Type and some 12-speed road/gravel models. Always verify compatibility with your specific setup.
