SRAM brought out the original single chainring 1×11 groupset, after a few years Shimano launched it’s own 11 speed spec offering 2×11 (soon followed by SRAM) and 3×11 in addition to the single chainring. Albeit with varying gear ratios, both companies however trickled the tech to their mid range groupsets, making the gearing more accessible. 
With the advent of 2×11 we felt the solution for an efficient all round gearing, away from 3x systems. In fact we cover gear ratios in Issue 38 of TREAD, The Great Chainring Debate

So is SRAM’s 12 speed the new thing? Who knows, it’s certainly adds to the debate and could be a solutution to 2x ratios for some riders. We can see an added benefit frame design and clearance too while also raising questions about wheel builds and chain line, we’re looking forward to a full review to let you know how it does in real world Saffer conditions. 
In the meantime you can read up on the information and pictures directly from SRAM below. – TREAD

 

SRAM introduced the first ever, purpose built 1x drivetrain, and is the absolute leader in 1x technology and innovation. We have manufactured, tested and ridden hundreds of thousands of SRAM 1x drivetrains, and have capitalized on the lessons learned from our experience to create all new drivetrains with Eagle Technology. Eagle drivetrains provide unparalleled performance, enhanced toughness and durability, and the freedom of a 500 percent gear range.

SM_XX1_EAGLE_Drivetrain_Gold_Side_M

In 2012, we introduced the world’s first purpose built 1x drivetrain — and it forever changed the way we ride. SRAM 1x changed the way we look at mountain bikes. Gone was the front derailleur, which immediately improved shifting simplicity and performance. It dropped a significant chunk of weight from the bike. It made shifting easier and consistently better for racers hitting the redline and new riders alike. It made mountain biking better for everyone. And it still does. We invented it, we build more 1x drivetrains than anyone else, and we are unrelenting in our commitment to furthering 1x technology.

Introducing SRAM Eagle Technology, our most advanced and highest-performing drivetrains to date. The new XX1 and X01 drivetrains, featuring Eagle Technology, are collections of components that have been engineered for a whole new level of ride quality and integration. These drivetrains have not only been refined, we have torn them apart, built them up, tested, tweaked, engineered and tested again. Eagle Technology delivers a drivetrain that is smoother, simpler, more durable and quieter than anything you’ve ever ridden. Add to that Eagle’s massive gear range, and you have greater freedom to ride how you want, where you want. Performance, durability, simplicity, range, freedom: Introducing Eagle, only from SRAM.

 

XX1 Eagle

We 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 our 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.

 

  • Eagle represents our newest 1x drivetrain technologies
  • Eagle is a lighter, tougher, quieter, more durable and more precise
  • Eagle features all-new 1x components, engineered for even greater durability and performance
  • Eagle has a significant weight advantage over other drivetrains—XX1 Eagle weighs up to 300 grams less than 2x drivetrains with similar gear range
  • Eagle technology allows an expanded, optimum, 500-percent gear range—a 20-percent increase over our other 1x drivetrains

 

XX1 Eagle 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.

Features and benefits

  • Groundbreaking new chain design and technology
  • The Eagle chain has been completely re-engineered, and is produced with new manufacturing technology.
  • All-new Eagle Power Lock chain connector with FLOWLINK technology provides better chain-guiding and increased longevity
  • The 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 on Eagle cassettes and rings

XG-1299 Eagle Cassette

Take a quick look at the new X-DOME Eagle cassette. The last dangling shred of an argument in favour 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.

XX1 Eagle Rear Derailleur

This new derailleur not only answers the Eagle drivetrain’s need for greater capacity, but is also the next evolution of our proven, 1x-specific X-HORIZON design. The larger, 14-tooth X-SYNC lower pulley, allows 10- to 50-tooth cassette capacity in this compact design, and also adds to Eagle’s overall smooth-pedaling feel. Our new, Type-3 ROLLER BEARING CLUTCH features a smoother torque curve for a quieter, more consistent operation and feel. CAGE LOCK has been moved back and out of the way, protecting it from trail debris. A redesigned, robust mounting system further improves the Eagle derailleur’s performance and overall durability.

XX1 Eagle Grip Shift

Three decades ago, SRAM was founded on a product called Grip Shift and an idea that shifting a bike should be easier, better and more intuitive. It’s more advanced than the original, but the all-new XX1 Eagle Grip Shift follows in the same tradition of making shifting easier, better and more intuitive. The new XX1 Eagle Grip Shift system includes new, robust internals that make it more durable and its’ shifting performance more precise. But just like the original, it is total control in the palm of your hand.

 

Features and Benefits

  • New Grip Shift mechanism takes SRAM’s original invention to an increased level of precision and durability.

XX 1 Eagle Chainring

The radical new look and feel of our X-SYNC 2 Eagle chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chainrings. We subjected every size of chainring to untold environmental and mechanical tortures, abuse and neglect, in both lab and real-world settings, to come up with a chainring that would augment the Eagle drivetrain’s performance in all conditions. The longer, positive-rake tooth shape has been designed to work perfectly with the new Eagle chain to increase chain retention and overall pedaling efficiency, while decreasing friction, noise and wear.

Features and Benefits

  • X-SYNC 2 chainring design increases chain retention, wear life, and reduces friction and noise.
  • Designed to be used with Eagle chain
