LTWOO TX or other cheap 12sp MTB derailleurs

[Dingus_Bingus420]

Does anyone have any experience with the ltwoo TX? It seems like a killer deal compared to sram and shimano, but there's almost no reviews or information about the groupset.

I'm pretty tired of hearing the usual bike shop talk about how everything other than sram or shimano sucks and breaks. Microshift has been pretty much flawless for me, and ltoo's road and electronic sets seem to be quality. Part of me wants to take the gamble, but I've honestly already overspent on this hardtail and a ~$60 gamble just isn't in the budget.

If anyone has tried it, or really any other mechanical ltwoo groupset I would love to hear your insight.

That’s what I fitted on mine and I am happy with it, although I don’t have any contemporary references. It’s easy to fit and dial in, very nicely finished, I wouldn’t hesitate to get another one.

What cassette and chain are you using? Also, would you say you're more of an XC rider or more aggressive? I'm mostly worried about the clutch, I hate dropping a chain after a jump or rut section.

I'm glad your setup is working well though, honestly I was super impressed by their electronic gravel set I got to see in person. Although I never personally see myself going electronic, it was one of the better 1x12 systems I've tried. I just wonder if the mechanical is receiving the same level of development.

Speedo 10-52T and YBN chain, not agressive at all, definitely more XC.

I fitted Ltwoo TX 1x12s on my 2017 Canyon Spectral.
Upgrading from 1x11s SRAM GX.

I combined it with 9-50T ZTTO ULT cassette and YBN 12s chain.

Shifting performance itself is good, I can't say its any worse than GX.
It is reliable, predictable, shifts OK under load.
Indexing is good, easy to setup.

Quality of the components seems good.
The only thing that is a bit "iffy" is the cable guide on the derailleur, it is plastic and looks like it could break easily if something would hit the derailleur. Will see how it holds up...

What bothers me is the ergonomics of the levers, GX has much nicer position of the levers.
On TX you have to place your finger in a bit weird position to shift.

I did not experience any chain drops so far, but I do not run extremely aggressive trails.
My riding is mostly XC.

Thanks for both your replies, based on a little more research and failing to hear anything back from ltwoo I ended up buying a mixed shimano groupset. For around the same $50 I got an m8100 shifter and m6100 derailleur, since I ride pretty aggressive trails I'm hoping the shimano's stiffer clutch is a better fit for me.

Knowing the development time of chinese companies I'm probably just a few months early to a beefier 12sp group being released, but for now I'm making the most of the big brand stuff.

With current pricing available on Shimano, it’s hard to overlook…

The chain tensioner on the TX looks the same as the gravel derailleur. Its not a true clutch and I would expect some chain slap with it on rough terrain. Mid level shimano stuff would still be a vastly superior product in my estimation.

As someone with very large hands, the sram lever positioning is way too cramped for me, i was running an XX1 lever with a gx derailleur on my race bike. the ltwoo thumb lever sits much lower, i'll run it this season and then see if i like it, but it seems very good

so, just received and installed the Ltwoo TX rear mech. shifts great, feels good, we'll see how it does. still waiting on my rockshox sidluxe to come back from warranty so i can't ride my bike right now. i'm definitely curious to see how it performs, for 45 euros it seems like it was a steal.

Edit: first impressions are amazing, it shifts perfectly. the shifter also feels very clicky, not mushy at all, beats the hell out of Shimano Deore. I'd say the shifter feels a bit like a Sram SX shifter, maybe a little better, it's nice and clicky, but of course it's not as good as something that costs 3x more. the derailleur also has zero lateral play, unlike most sram eagle mechs. build quality feels great. we shall see how it holds up. As for the clutch, there's very little chain slap, in fact, i'd say the clutch is better than a Sram GX, it's very good. And it's adjustable too, so that's nice. Loving it so far.

Edit 2: the big paddle on the shifter does have a little lateral play, so i'd say the shifter is really on the cheaper feeling side, it does feel very clicky and not mushy at all though. if i was assembling it now, i think i'd pair a sram SX shifter with an L-twoo TX derailleur.
