BlackTech

Stays black permanently. KMC BlackTech is not a mere coating; it's a surface treatment that integrates the color into the material. The process involves two steps: first, each individual chain component is treated, and then the procedure is repeated with the assembled elements. As a result, the chain maintains its deep black color permanently and exhibits exceptional rust resistance.

Advice
Derailleur gears are expected to withstand external weather conditions and hard continuous stress and transmit the rider‘s shifting impulses smoothly and quietly. Today, high-quality materials and coatings as well as constructive fine-tuning (e.g. x-Bridge) of the chain links enable a long service life with regular chain maintenance. However, the chain should be checked regularly and the chain longation checked with a chain gauge. The wear of the chain is highly dependent on the type of application and the shifting behaviour of the driver. Worn chains also accelerate the wear of the other – usually much more expensive – drive components.
Chains for derailleur systems are subject to special requirements due to the design of these systems. To prevent increased wear and to maintain good shifting performance, the chain should be cleaned and maintained regularly.
