SRAM just released their new NX Eagle 1×12 drivetrain. The total system is $120 cheaper than GX Eagle and weighs just under a few hundred grams more. Here are the details…

Folks got pretty excited when SRAM launched their relatively affordable 12-speed GX Eagle drivetrain last year. With much of the same performance as the pricey X01 Eagle, at half the cost, it opened up 1×12 to the masses. Just announced today, the even more affordable NX Eagle features the same technology and drops the price tag even further. Not to mention, NX makes 1×12 possible without an XD freehub driver.

What will be very interesting to many riders is the fact that SRAM 86ed the XD driver body for NX Eagle. Instead, the PG-1230 12-speed cassette mounts on a standard 8, 9, 10-speed splined Shimano or SRAM driver. This means one fewer expense required to upgrade to 1×12. And, of course, the biggest draw with Eagle NX 1×12 is the price of the full drivetrain. We’ll start with that and you can find standard press-time details on each component below:

  • NX Eagle Trigger Shifter $42 / 112 grams
  • NX Eagle Rear Derailleur $107 / 339 grams
  • NX Eagle PG-1230 Cassette $100 / 615 grams
  • NX Eagle Chain $26 / 278 grams (126 links)
  • NX Eagle DUB Cranks $105 / 705 grams (175mm, 32T ring)

All told, the $380, 2,049 gram SRAM Eagle NX 1×12 drivetrain is about $120 cheaper and weighs 299 grams more than the full GX Eagle (excluding XD Driver), which comes in at 1,741 grams. NX Eagle components will be on sale in September of 2018. Here are details taken directly from SRAM’s press for each component:


“The SRAM NX crankset delivers Eagle™ styling and performance to the newest addition to the Eagle™ ecosystem. Designed for SRAM’s X-SYNC™2 chainrings, the NX crankset is engineered for complete chain control—each tooth’s profile is precisely engineered to work quietly, efficiently and securely with the Eagle™ chain’s inner and outer links. DUB™ technology features a better-engineered bottom bracket and a new spindle design, which together allows 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 performance and durability.
