New SRAM 12-Speed Eagle 1x Drivetrain


“Tranquility Base here. The Eagle has landed.” Ok, SRAM haven’t quite pulled off something as cool as landing on the moon, but the new Eagle 1×12 (yes, twelve) drivetrain is some pretty exciting stuff!

You can read all the details below, but in a nutshell, the new SRAM Eagle drivetrain is a single-ring specific, 12-speed system, with a MASSIVE 10-50 tooth cassette range.

A 500% gear range with a single ring is new ground – SRAM’s stated aim is to kill the front derailleur for mountain bikes, it’s their clear point of difference with Shimano, and this is their biggest weapon in that battle to date. Put simply, this spread is the kind of gear range that was previously the domain of double (or even triple) chain ring drivetrains.

If this stuff lives up to expectations in the real world, it’s certainly going to silence a lot of critics who’ve maintained that current 1×11 drivetrains don’t offer a big enough range for the masses.

To cover such a huge gear range without unworkably large jumps in the gear ratios, SRAM decided 11-gears wasn’t enough. Fitting another gear into the mix (using the same freehub, thank god) was the answer. This cancels out any interchangeability between equipment, you can’t just bung a new 10-50 cassette onto your existing SRAM GX, X1, X01 or XX1 drivetrain. You’ve got to go all in with Eagle, baby.

While the gear range offered by Eagle should be broad enough for any rider, in just about any situation, the pricing is certainly not in the realms of the average punter. There are two levels of Eagle available (XX1 and X01) but still, the thought of handing over $629 for a cassette makes us feel like we’ve licked a 9-Volt battery. But that’s the reality of having equipment that’s on the cutting edge – R&D doesn’t happen for free, folks! Of course people will pay it, because that’s the price of having the equipment that’s on the cutting edge – And of course pricing will drop over time as the technology trickles down to lower levels in the SRAM range, but in the short term, you’ll need to open your wallet a fair way to experience what Eagle is all bout.

The gear range wars are entering a new phase now. Along with Eagle, we’ve also recently seen the announcement from Shimano that they’ve got a new 11-46 tooth XT cassette on the way, plus there’s a proliferation of products from smaller companies making accessories to extend the range of existing 1×10 and 1×11 systems (like these).

That’s enough from us for now, we’ll bring you more once we’ve actually got this stuff in our hands to ride. Below you’ll find all the details from SRAM, along with Australian pricing.


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 capitalised 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. 

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.

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-optimised 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.

XX1 Eagle™ Chain – $169.95

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.

Eagle™ Chainring

SM_XX1_EAGLE_Crank_24mm_32t_Black_Front_M

 

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 pedalling efficiency, while decreasing friction, noise and wear.
