Sram XX1 EAGLE MTB Bicycle Chain

It may look normal from the outside, but the engineering inside this incredible new chain design makes possible a gear range previously only found in dual-ring drivetrains.. And it's also the single biggest contributor to the Eagle™ transmission's ultra-smooth, precise, durable and quiet operation.. Eagle™ chain links have a smooth radius with no sharp edges or chamfers, resulting in significantly reduced noise, friction and wear on chains and cassette teeth. This design also allows for a flatter plate, meaning more uniform chain riveting and greater overall strength.. HARD CHROME™ technology extends chain life, while Titanium Nitride coating on Gold and Black models reduces corrosion and further reduces friction. Peculiarities: - Innovative chain design and technology - The Eagle™ chain has been completely redesigned and is manufactured using new manufacturing technology - All-new Eagle™ PowerLock® chain connector with FLOWLINK™ technology provides better chain guidance and longer life - XX1 Eagle™ chain is the quietest, strongest and most wear-resistant chain in the world - Unique features and design also provide significantly improved wear resistance for Eagle™ cassettes and rings Specifications: - Core technologies: FLOWLINK™, HARD CHROME™, POWERLOCK®, X-SYNC™ - Compatible Gears Eagle™ 10-50T Cassette Only - Closing link: Eagle™ PowerLock® PVD - Outer plate: Nickel + PVD gold or black - Inner plate: Chrome plated + PVD gold or black - Pin processing: Hardened Chrome, Hollow Pin™ - Speeds: 12 - Compatibility: Eagle™ Technology: Flow Link: - Ultra-smooth internal chain plates are completely free of square edges, resulting in the chain engaging the cassette and sprocket with much less friction, resulting in quieter operation and longer life. The design allows for a narrower overall profile that can handle larger angles, and also allows for a flatter outer plate, meaning more uniform chain riveting and increased overall strength. HARD CHROME™: - SRAM HARD CHROME™ chain has four times the elongation resistance (wear and tear), than our other chains. This is due to a new finishing process for the inner links and rollers.. The push pin strength and ultimate strength are equivalent to our current chains. HARD CHROME™ chain lasts longer and is just as strong. PowerLock®: - SRAM chain engineers developed PowerLock® as a reliable, consistent way to connect our chains without tools.. While PowerLock® requires no special tools for installation, the particularly tight tolerances of 10-, 11- and 12-speed transmissions require that each PowerLock® be good for one-time use only. X-SYNC™: - SRAM X-SYNC™ 1x chainrings deliver the highest levels of performance and durability. SRAM X-SYNC™ tall square teeth engage the chain earlier than traditional triangle teeth. The sharp and narrow tooth profile and rounded chamfers help to cope with chain sag. To ensure the best performance in muddy conditions, X-SYNC™ sprockets have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1x™ drivetrain.
