XX1 Eagle™ Crankset

LIGHTER. STIFFER. STRONGER.

True competitors are always looking for a performance advantage—a relentless pursuit of equipment that is lighter, stiffer and stronger. To create the best drivetrain possible, we started with a completely reengineered crankset design. Our all-new XX1 Eagle™ crankset is the lightest, stiffest and strongest on the market. A special hollow internal architecture, combined with our proprietary CARBON TUNED™ lay-up, allows us to build a lightweight and ultra-energy-efficient crankset perfectly suited for the high-wattage output and smooth style of cross country riding and racing. Teamed up with a new Eagle™ direct mount chainring, and as an integral part of the Eagle™ drivetrain, the new XX1 Eagle™ crankset puts more focused power into every ride.

  • The lightest, stiffest, strongest crankset available
  • All-new crank-arm design optimized for cross-country and trail applications
  • All-new SRAM CARBON TUNED™ crank technology provides extreme stiffness and light weight
  • All-new chainring technology is designed specifically for Eagle™ chains and drivetrains
  • The X-SYNC™ 2 chainring provides significantly quieter performance, with better mud clearing and extraordinary durability

Technology

BB30

Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.

CARBON TUNED™

Strength and stiffness where you need it, lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.

GXP®

GXP’s Gutter Seal design cuts friction and weight—improving both feel and performance.

Read More

PressFit™

A variant of the external GXP bottom bracket, PressFit cuts weight by up to 40 grams and eases installation by allowing you to press the bearing cups into the frame instead of threading them. It requires no change to the crank spindle length and diameter.

Pressfit 30™

This is a new design led by SRAM. It’s all the best from BB30 and Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30mm spindle cranksets. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life. Frames will need a 46mm inner-diameter bottom bracket shell to accommodate this system. PressFit 30 for road will require a 68mm wide shell while PressFit 30 for MTB will require a 73mm wide shell. Advantages: Huge weight savings, narrow Q-factor, more ankle clearance, greater bearing durability, stiffer/stronger crank construction, simple installation. Allows for larger diameter frame tubes increasing frame stiffness. Drawbacks: Still searching.

X-Sync 2

X-SYNC™ 2 Eagle is the next evolution of SRAM X-SYNC™ technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC EAGLE™ design reduces friction and the accumulation of mud, grit and grime.

SRAM XX1 Eagle | SRAM X01 | mtb-mag.com | March 2016

“We loved the fact that we could pedal(ride) faster on the downhills: with the 34-10 it’s easy to reach 40 km/h pedaling, and this can be an advantage when racing. Combined to the fact that the 50T cog allows to climb every steep trail in sight, the Eagle reaches the purpose of widening the reach of the single chainring drivetrains, even for those who felt the 1×11 was too short, both for racing and for recreational purpose.”

"SRAM Eagle 1x12 | The Front Derailleur Killer" - VitalMTB.com

With a highly positive and thorough feature on both XX1 Eagle™ and X01 Eagle™ they concluded - "With gear range out of the picture, there are now very few arguments left for not switching to a simpler, quieter, and easier-to-use 1X drivetrain...

SRAM XX1 & X01 Eagle™ - Pinkbike's first impressions

"The most immediate sensation was just how smooth the drivetrain felt. Sure, a brand new drivetrain will always feel better than one that's had the snot beat out of it for months, but this was something different. The interaction between the chain and chainring feels absolutely seamless, almost as if it were somehow one unit rather than two separate components."

SRAM XX1 Eagle | First Ride - MTBR.com

"SRAM has trumpeted a host of non-gearing related improvements between its 1×11 and 1×12 drivetrains, it’s the gearing that will always draw the most attention...you now have a full 500% range, which on the bike feels a lot like what you get from a traditional 2x system, just with one less derailleur and shift lever."

 

"But when you add a 50-tooth cog to the equation, the front derailleur becomes obsolete, which forever minimizes cockpit clutter."
