@Gavalar I never said I have no experience with CUES. Nor did I say you need XT. If you want cheaper option to with deore it will serve you a lot better.
I'm talking strictly only about the MTB sets I have zero experience with sets outside MTB range.
To start of I think you need a reality check if you think "emt specific" is a real and needed thing lmao. Same goes for the emtb forks. Don't believe every marketing talking point.
"...cues= linkglide.". Okey... You clearly have no idea what you are talking about. Even though CUES uses linkglide doesn't mean cues= linkglide.
CUES mech and shifter are absolut crap.. I mean you get what you paid for. There is a reason why it's the cheapest version and you can clearly see and feel it.
If you want to choose the cheaper option then go with deore as hg or linkglide version depending which systems pros/cons you value for your personal use. If you want something better then choose XT shifter. Deore mech will work more than fine.
If you want more specific details why you should avoid CUES there are tons of proper reviews everywhere. Even on here. Here's a link to one which is worth a read.
