Extremely durable - extremely precise
KMC`s chains of the DLC series with titanium-carbon-nitride coating have an extremely hard surface and thus reduced friction. The result: smooth running, optimal switching behavior and, due to the extreme hardness of the bolts, an above-average service life of the entire drive.
Highlights
- Extremely light, extremely precise
- Extremely durable due to 4-fold surface treatment
- Precision chamfering of the inner and outer plates for perfect switching behavior
- DLC12 for SRAM 12-speed switching groups
- DLC - Diamond Like Coating
- Not directional
- Durable

Technologies used
In this chapter we explain the technologies that the manufacturer uses for this product.
X-Bridge
Precisely chamfered outer link plates with precisely defined angles enable quick and precise switching operations.
Durability Warranty
With this seal of approval, KMC guarantees that a KMC chain will last longer than comparable chains from other brands. This benefit extends to the series DLC, XSL, XEL, XL, X101 and e-bike chains.
DLC
The main feature of the DLC coating (Diamond Like Coating) is the extraordinary surface hardness and the associated reduction in wear caused by abrasion. The properties of the high-end series: an outstanding service life, the best switching properties and a consistently beautiful appearance of the DLC 10 to 12-speed chains.
scope of delivery
- 1 x KMC DLC12 chain (see item description for details)
