For competitive racing or mountain biking, groupsets are everything, and among them, the 1x setup groupsets have taken over.
And from the setups, the Sram NX and GX are undoubtedly the most popular.
Even though both have 1x drivetrain and provide the same gearing, there are quite a few differences. This, as a result, started the sramnx vs gx discussion.
While all 1x setups have similar benefits and have fewer shifters, derailleur, and cable, we will be focusing on the NX and GX setups.
Our deep dive into them both will let you know all that is different between them.

Sram NX or Sram GX?
It’s a known fact that the GX is more expensive than the NX and is more for high-end customers.
Besides the apparent and obvious $100 price difference between them, we’ve also come to find some major and minor differences in the overall groupsets.
The NX groupset’s crankset, made of 6000-series alloy or aluminum, is strong but a bit heavier and less durable.
Similarly, the crank’s steel chainring also adds to the weight of this entire 1x drivetrain system. The rear derailleur’s material is a mixture of steel and aluminum.
On the other hand, the GX groupset’s crankset, made of 7000-series alloy or aluminum, is more solid, durable, and lightweight.
Besides, the crank’s alloy chainring further adds to the drivetrain’s lightweight nature. In this case, the rear derailleur’s material is entirely aluminum.
Shifters and Chains
The NX groupset being cheaper, the shifters have an entirely plastic body. Unless you crash often, this doesn’t affect much on the durability or lifespan of them.
Besides that, the chain, made from unalloyed steel plates, adds more weight to it.
When it comes to the GX, the shifters’ metal lower part adds to its durable frame.
The chains come with a chrome finish, which ups the price further and also makes it durable.
Usually, the cassettes of the NX come with loose gears. The gears have plastic spacers between them, making it ideal and fitting to use on any standard splined free-hub, most commonly a Shimano HG splined hub. It has an 11-50 cassette 455% range.
However, the GX groupset cassette has pinned cogs, which makes them a one-piece gear.
It thus lives up to its full metal geared set quality. Besides that, it has a 10-50 cassette 500% range for a smoother ride.
