Specifications: Application: Road, MTB, E-Bike, City & Touring Gearing: 11-speed Technical Information: Links: 116 Closure Type: chain pin with pointed end Pin Type: chromed, solid Directional: yes Recommended Groupsets: 105 5800, SLX M7000-11, STEPS E8000, STEPS E6000 Material: steel Features: - super narrow HG-X11 chain for 1x11, 2x11, 3x11 - same durability as current 10-speed chains - smooth and precise shifting - inner plate SIL-TEC, outer plate grey Technology: SIL-TEC Superior to simple coating, SIL-TEC is an advanced plating process that improves system performance through the use of imbedded fluorine particles. SIL-TEC products run smoother and wear longer in all conditions. Directional The CN-HG601 chain has a unique, asymmetrical design. The specially formed plates optimize the interaction between chain and cog as well as smoother shifting under load. The inner side is optimized for rear HG (Hyperglide) shifts and ensures fast and precise shifting. The outer sided is optimized for chainring shifts. The sides of the chain are marked to ensure that the chain is correctly assembled. The side with the markings is the outer side. Warning: The high shifting performance is achieved only through proper assembly. If the chain is assembled incorrectly, the chain may fall which may lead to serious injury.
