XG-1299 Eagle™ Cassette

FREEDOM

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

  • SRAM’s cassette manufacturing technology provides the greatest durability and lightest weight
  • All-new shifting features create a smoother, quieter system with enhanced inboard and outboard shift performance
  • XD™ driver body compatible
  • 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50

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 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."
