Derailleur Chains

derailleur From trekking bikes to racing bikes, derailleur gears are the classic when it comes to sporty riding. While 10-speed derailleurs were the measure of all things a few years ago, the manufacturers have now reached 12-speed derailleurs. This means more gradations for the rider, but significantly higher demands on construction and material. As a true specialist, we always have the necessary know-how to master the challenges of the market. The most precise production technology, innovative surface treatment and the most modern riveting technology are consistently combined in our products. Tested by top athletes on the road and off-road and used in races under the toughest conditions, KMC chains are the guarantee for maximum driving pleasure.


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.
