SRAM Introduces 10-52T Eagle GX Drivetrain

SRAM just dropped some very exciting news with the announcement of an all new and very much improved GX Eagle drivetrain. While it’s covered in full detail below, first off the new cassette has a widened range – via 10-52T gearing it went from 500% range to 520%. The new rear derailleur sees a host of refinements and there is now a carbon fiber crankset being offered. Lastly, there is a single click shifter which is great for e-bikes. XO1 and XX1 drivetrains also see some updates with the new, wider range …



The new 10-52t Eagle cassette for riders who prioritize all day function over anything else. With an expanded, 520-percent gear range giving riders more ability to spin and recover on the burliest climbs. Featuring FULL PIN technology that uses lightweight, precision engineered steel cogs permanently connected with high-strength stainless steel pins. An open design similar to our X-DOME cassette that aids in mud clearance, giving riders crisp shifting performance and longer component life.  

  • 520-percent gear range utilizing the industry standard XD hub driver 
  • Light and strong FULL PIN technology similar to X-DOME bringing true 1x gear range to more riders and builds  
  • Lunar and black colorway makes the XG-1275 cassette right at home on any build


Riders want the derailleur to do its job shifting on command, whether under climbing load or the stage finish. The GX Eagle derailleur gets it done with an updated cage architecture that improves chain management. Refined to work with the new 10-52t cassettes, it’s also backwards compatible for the 10-50t versions. Finished with the new GX Eagle master colorway—to compliment any cassette and chain colorway a rider wants from the Eagle Colorsystem. Further proof that the GX Eagle derailleur is there for one thing—to do the job. 

  • Backwards compatible, works with both 10-50t and new 10-52t cassettes
  • Updated cage architecture provides better chain retention and precise shifts
  • Comes in GX Eagle master colorway as part of Eagle Colorsystem and goes with all colors of Eagle cassettes & chains—from Black to Gold to Rainbow and new Copper


The SRAM carbon GX Eagle crankset delivers consistent performance every time out. Featuring SRAM’s X-SYNC 2 tooth profile chainring, the Carbon GX crankset is engineered for complete chain control. Each tooth’s thickness is precisely toleranced and controlled to work seamlessly with the chain’s inner and outer links. DUBtechnology features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure
of durability.
