SRAM built the incredible new XX1 Eagle™ drivetrain to work quietly, intuitively, precisely and perfectly. Whether you're an hour and twelve minutes into a World Cup XC or, just about to hit the top of Pearl Pass-XX1 Eagle™ is ready for that and every place in between. This cross-country-optimized drivetrain combines the newest generation of SRAM 1x™ drivetrain technological advancements with lightweight materials. With a greater gear range of 500-percent, XX1 Eagle™ gives you smoother, more precise shifts with greater durability for long lasting performance so you can spend more time in the gear you want. XX1 Eagle™ just rewrote the rules of freedom.
It might look normal from the outside, but the engineering inside this incredible new chain design that makes possible a gear range previously found only in 2-chainring drivetrains. And it's also the biggest contributor to the Eagle™ drivetrain's ultra-smooth, precise, durable and quiet performance. The Eagle™ chain's links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear on chainrings and cassette cogs. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. HARD CHROME™ technology extends the chain's optimal performance life, and a Titanium Nitride coating on the Gold and Black models decreases corrosion and further reduces friction.
- Groundbreaking new chain design and technology.
- The Eagle™ chain has been completely re-engineered, and is produced with new manufacturing technology.
- All-new Eagle™ PowerLock® chain connector with FLOWLINK™ technology provides better chain-guiding and increased longevity.
- The XX1 Eagle™ chain is on of the quietest, strongest and most wear-resistant chain in the world.
- Unique features and design also provide significantly improved wear resistance on Eagle™ cassettes and rings.
SRAM X-SYNC™ 1X chain rings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings 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.
Ultra-smooth chain inner-plates are completely devoid of square edges, resulting in a chain that engages the cassette and chainring with far less friction, for quieter performance and better wear life. The design allows a narrower overall profile that can withstand greater angles, and also allows for a flatter outer-plate, which means more consistent chain riveting and enhanced overall strength.
The XX1 Chain has 4 times the elongation (wear) resistance to our other chains. This is due to the new finishing process on the inner links and rollers. Push pin strength and ultimate strength are equivalent to our current chains. The XX1 Chain lasts longer and is just as strong.
SRAM chain engineers developed PowerLock as a tool free, sure and consistent way to connect our 10 speed chains. While PL does not require special tools for install, the especially tight tolerances mandated that each PowerLock is good for a one-time application only.
