X01 Eagle™ Rear Derailleur

PURPOSE

This new derailleur not only answers the Eagle™ drivetrain’s need for greater capacity, but it’s 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 relatively 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. And a redesigned, robust mounting system further improves the Eagle™ derailleur’s performance and overall durability.

  • Completely redesigned rear derailleur incorporating our proven X-HORIZON™ design and new Type-3 ROLLER BEARING CLUTCH™ technology
  • Re-engineered mounting system and repositioned CAGE LOCK™ add robustness
  • Eagle™ pulley technology provides greater efficiency, crisper shifting and quieter
  • Aluminum cage and lightweight hardware make it light and tough

Technology

CAGE LOCK™

With CAGE LOCK™ technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.

ROLLER BEARING CLUTCH™

ROLLER BEARING CLUTCH™ rear derailleurs deliver maximum drivetrain stability—even through the most punishing terrain. With ROLLER BEARING CLUTCH™ technology, derailleur bounce and chain slap are eliminated without sacrificing precision.

X-ACTUATION™

Developed specifically for SRAM 1x™, X-ACTUATION™ keeps shifting sharp and consistent across the entire cassette.

Read More

X-HORIZON™

The X-HORIZON™ rear derailleur’s ‘straight parallelogram’ design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.

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.

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."
