The GX Eagle Has Landed – An Affordable 12-speed Drivetrain

by Brian Mullin on June 8, 2017

The new SRAM GX Eagle has landed, and it brings their 12-speed 1x drivetrain technology to a wallet-friendly $495 price point. The trickle down of the Eagle Technology from the XX1 and X01 groups has been brought down to the GX Eagle pricing, so shifting and performance should feel the same. All the GX Eagle parts are compatible with any other Eagle system, so you could mix and match things as desired. The affordable GX Eagle will make a lot of people convert their bikes to a 12-speed drivetrain this year, and if you skip installing a new crankset, you can drop another $100 from the price.

The new SRAM GX Eagle drivetrain comes in at a much more affordable $495:

  • Cassette: $195
  • Derailleur: $110
  • Shifter: $40
  • Crank: $120
  • Chain: $30
  • Total: $495

To keep the costs down on the new GX Eagle, the parts are not as nicely finished, use different materials and manufacturing methods, so the weight bumps up almost 1/2 pound heavier than the X01 and XX1 Eagle groups:

  • Cassette: 455 grams
  • Derailleur: 290 grams
  • Shifter: 122 grams
  • Crank: 610 grams
  • Chain: 270 grams
  • Total: 1717 grams

XG-1275 Eagle Cassette

Ride anywhere with this wide range XG-1275, 10- to 50-tooth Eagle cassette that provides the right gear. Fast on the flats. Control on the climbs. Dictate your own pace, anywhere. Only Eagle technology is the 1x drivetrain engineered for infinite freedom. FULL PIN technology uses lightweight, stamped steel cogs held together with high-strength stainless steel pins. The result: a cassette that’s light and strong. The open design similar to our X-DOME cassette aids in mud clearance, giving you cleaner shifting performance and longer component life. New X-GLIDE 2 improves both inboard and outboard shifting, as well as chain retention.

GX Eagle Rear Derailleur

This new GX 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, 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.
