SRAM XX1 Eagle Wear and Tear -Set with Chain and XG-1299 Cassette - 50 teeth - gold

The Wear and Tear Set for the XX1 Eagle consists of:

• SRAM XX1 Eagle Chain 12-speed
• SRAM XG-1299 Eagle Cassette 12-speed - 10-50 teeth

XX1-Eagle 12-speed chain

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.

Technologies of the SRAM XX1 Eagle 12-speed chain

X-SYNC™

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.

Flow Link

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.

HARD CHROME™

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.

PowerLock®

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.

XG-1299 Eagle Cassette -12-speed - 10-50 teeth

Take a quick look at the new X-DOME™ Eagle™ cassette. The last dangling shred of an argument in favor of a mountain bike front derailleur is now officially dead. Designed for use with our proven, reliable XD™ driver body, this 12-speed, 10- to 50-tooth cassette offers an optimal 500-percent gear range at a considerably lighter weight than 2x systems. It carries with it the X-DOME™ architecture, which, independent tests have concluded, yields the strongest cassettes on the market. New shifting characteristics improve both, inboard and outboard shifting, as well as chain retention. 

Highlights of the XG-1299 Eagle cassette

• SRAM's cassette manufacturing technology provides the greatest durability and lightest weight
• All-new shifting features create a smoother, quieter system with enhanced inboard and outboard shift performance
• for XD™ driver body only
• 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50 - teeth

Technology´s of the SRAM XG-1299 Eagle cassette

X-DOME™ - X-DOME technology creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.

X-Glide™ 2 - X-GLIDE™ 2 is next generation of SRAM X-GLIDE™ technology optimized for the EAGLE™ 12-speed cassette. It provides quick, precise, power-on shifting performance throughout the gear range, and increases chain retention on larger cogs.

Eagle™ - Eagle technology represents the newest SRAM 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions.

XD™ Driver Body - XD is a new cassette driver body design that allows the use of a 10 tooth small cog and provides an improved interface with the cassette.
