SRAM introduced the first ever, purpose built 1x drivetrain, and is the absolute leader in 1x technology and innovation. It’s always been a favourite here at Dirt and again is one of our picks in the 2016 Dirt 100.
SRAM have manufactured, tested and ridden hundreds of thousands of 1x™ drivetrains, and have capitalized on the lessons learned from their experience to create all new drivetrains with Eagle™ Technology. Eagle™ drivetrains provide unparalleled performance, enhanced toughness and durability, and the freedom of an increased range of gears. Most riders who have tried an eleven speed 1x drivetrain love its simplicity, silence, chain security and low weight. Others may feel they lack just one or two lower gears, yet don’t feel they want to compromise the top end ratios (and potentially suspension action) by fitting a smaller chainring. This new transmission from SRAM answers those questions.
This new Eagle technology from SRAM is split into two main component levels, XX1 and X01. It’s the X01 that looks the most relevant to the bikes we run here at Dirt. First up, here’s the overview from SRAM and who their focus is on with this kit.
BORN IN THE USA, ENGINEERED IN GERMANY, MADE FOR THE WORLD
SRAM XX1 Eagle™ – NEW RULES
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.
SRAM X01 Eagle™ – FEARLESS
The X01 Eagle™ drivetrain signals an exciting new era of freedom and the next level of uncompromising performance for enduro racers and aggressive trail riders. Watching the world’s best racers use our parts to battle against nature, physics and time itself, has inspired us to supply them with the most advanced tools we can develop. X01 Eagle™ takes everything you love about our pioneering 1x drivetrains and increases its wear life, toughness, precision, smooth and silent operation. Add to that the 10- to 50-tooth, 12-speed, Eagle™ cassette, and you have a range of gears that gives you the freedom to enjoy the benefit of 1x in any terrain, any location and at any speed. X01 Eagle™ is drivetrain freedom—how you exploit it is up to you.
X01 EAGLE
X01 Eagle™ takes everything you love about SRAM’s pioneering 1x drivetrains and increases its wear life, toughness, precision, smooth and silent operation. Add to that the 10- to 50-tooth, 12-speed, Eagle™ cassette, and you have a range of gears that gives you the freedom to enjoy the benefit of 1x in any terrain, any location and at any speed. X01 Eagle™ is drivetrain freedom—how you exploit it is up to you. X01 Eagle™ Chain Silence 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.
KEY POINTS WITH THE NEW X01 EAGLE:
SRAM’s 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.
This new technology has a significant weight advantage over other drivetrains—XX1 Eagle™ weighs up to 300 grams less than 2x drivetrains with similar gear range.
New cassette innovation allows an expanded, optimum, 500-percent gear range—a 20-percent increase over our other 1x drivetrains.
