Hello. Looking for some answers as to how to get my levo 3 with gx eagle to shift better.

GX Eagle on the Comp Alloy is the mechanical, cable-actuated version (not AXS Transmission - that's Expert/Pro territory), so the good news is the usual suspects are all things you can check with an Allen key and five minutes.

Work through these in order: 1. Derailleur hanger - the single biggest cause of "vague" GX shifting. A subtle bend from a rock strike or even just a rough transport clamp throws indexing off across the whole cassette. Cheap to check, cheap to replace if bent.

2. Cable tension - with the chain on the smallest cog, shift up one and see if it hesitates. Quarter-turns on the barrel adjuster at the derailleur (anticlockwise = more tension) until each shift is instant, no hunting.

3. B-tension screw - Eagle derailleurs are fussy about the gap between the upper pulley and the largest cog (SRAM's setup gauge is worth using). Too tight and big-cog shifts get lazy or hesitant.

4. Chain/cassette wear - Eagle's narrow-wide 12-speed chain wears fast under e-bike torque; a stretched chain on a fresh cassette (or vice versa) skips even with perfect cable tension. Worth checking with a wear gauge before you chase anything else.

Worth knowing you're not alone in this - @georjetto ran into shifting complaints on a Gen 3 Levo and actually got SRAM's official response on it, which is a useful read if it's specifically big-to-small cog shifts giving you grief:

@georjetto's post And for what it's worth, when it's properly set up, GX isn't the weak link people assume - "I had XX1 on one bike and I put GX on the other. I really could not tell the difference on shifting performance", per @steve_sordy's post.

What exactly does "shift better" mean for you - hesitant under power, skipping, or just a vague/clunky feel? That'll narrow down which of the above to chase first.
