Hi! Looking for some user feedback. I am currently riding a 2019 full susp with 1x NX drivetrain. No issues with it, but see a lot of good, bad and ugly being said about that line. Is the GX line thatamuch better? Would I benefit from upgrading to GX, or should I consider going a step higher? I am NOT a basher, speed demon, or jumper.... just an old man that enjoys riding most everything and wants things to work good. Thanks for any assistance! Ron

The big differences are the materials are better quality and the feel of the shifts. I wouldn't go to x01 or xx1 unless you care about shaving weight or need the best level shifting from sram.

If the NX rear mech is fine, keep it until you have to replace it (if it gets play or you destroy it). Consider replacing the shifter with a GX. It's a pretty cheap upgrade and the alloy levers feel so much better than the plastic NX. The NX shifter feels cheap. I mean, it works fine, but it's a night and day difference in feel. The X01 shifter gets you adjustable levers (plus you can swap out for a PNW shifty lever to match a loam lever), but it costs nearly 3x the GX. My dropper lever is oneup, so I wasn't tempted by the matchy matchy since they don't make a shifter lever (yet).

I'm running an NX cassette despite the weight (167 gr more than gx iirc) because it is a wear part and it isn't worth it for me. I'm on an alloy frame and that 167gr is basically a rounding error. 11 tooth is fine (10 tooth isn't gonna buy me much) and I don't feel like spending an extra $70 on a hub driver plus a new GX cassette.

Update: I decided to stay with the NX system. Did a bit of adjusting to the B-gap, cable tension, and indexing of the derailleur. Those few things made a difference, enough to make me stop thinking of changing components. But still noticed "noisy and clunky" shifting and noted lateral play in the derailleur especially when chain tension was relaxed. I bought the b-bolt kit for the X01 Eagle derailleur, and took all of about 3 minutes to swap it in place of the NX one. Totally different design to it, and it honestly made it fell like a totally different bike. Ininstalling, I never even had to unclamp the shifter cable from the NX derailleur, old b-bolt out, new one in. World of difference, fast, crisp, quiet shifts. Cheap upgrade, with huge results!

Good to hear. I read about the XO1 b-bolt kit on another forum and was tempted to do it for my GX. Eagle seems finicky period, but when it's working well it is great. Fast, crisp and quiet just like you said.
