LTWOO RX hydro sets

[KvotheTheRaven]

I also wish they'd start selling the hydraulic components separately, I don't really need the derailleurs. Ltwoo stuff works with the Shimano 11/12 speed pull ratio.

This seller has them separately. There is also a 10sp version now, about 100CAD cheaper than 12sp.

Wow. I really should’ve waited a few more weeks. More options will for sure bring prices down.

Nice! Though I'm kicking myself for not buying used Shimano R7020 shifters that were selling for $200 USD locally. My buddy bought it for that price!

Maybe I'll wait for the next AliEx sales event to drive these prices down even further. Also I'm fine with alloy, I'll just cut the weight from my gut or carry less water! lol

I see the electronic groupsets are about to become a thing

[KvotheTheRaven]

This seller has started to sell the groupsets with the Zrace XG brakes instead of the Lt-woo ones. It's interesting that the seller call themselves the Lt-woo official store, however.

One could have a pretty light groupo for cheap..

Prices are also dropping. Not only that, but the shipping has as well, at least in Canada. Used to be around 50 CAD, now it's free.

Here's the link. Kinda long but I'm not sure how to shorten it. Sorry.

Is the XG a true flat mount brake? I have read the LTwoo caliper bolt spacing isn't a true flat mount and hence the bag of brackets?

[kbike]

Yes the xg are flat mount. I have them already.  They are 100g lighter than the l twoo calipers with 160 rotors.  With 160/140 I'd say about 120g lighter. You still need the bracket for front caliper with xg and other flat mount models. They use the same pad size.  I think they put in the l03a copied pads on the xg.

I haven't swapped them yet. Had a wicked gravel race yesterday and wasn't going to chance not bleeding them fully during the swap.

Quoting from 318Bike https://www.aliexpress.com/item/1005005385673438.html

In order to avoid SHIMANO's patent, LTWOO's Hydraulic Disc Brake Caliper uses a 70mm spacing mounting seat, and then installs it through an adapter, so that not only the Caliper is heavy, but the adapter is also very heavy, and the most important thing is that for some frames It is still not compatible, so we replaced the Flat Mount Caliper of ZRACE XG, so that the whole set can reduce weight 120g! and can be compatible with all flat mount frames and Forks.

Prices is definitely dropping.... 11s https://www.aliexpress.com/item/1005005385754066.html

Is there a listing for only hydraulic shifters? I tried and couldn't find one for hydros. There are plenty for mechanical/rim brakes though.

Not that I've seen. That's why I ordered the alloy groupset during the anniversary sale for almost $200 USD. Though I'm bummed it didn't come with the ZRace hydraulic calipers. 120g savings is like carrying a spare bike stem in your pocket! I'm not a hardcore weight weenie, but I don't like carrying pointless weight.

That was a good price. A while ago I was sitting on 105 hydro shifters that I sold because I don't like to keep parts lying around for long and now that I need them back, I am not finding anything reasonably priced anywhere in the used markets. Bummer :| So decided to look into Ltwoo/Sensah but no one sells just the shifters. Any idea if olives, barbs and oil pressure exerted by LTwoo shifters are same as needed by Shimano 105/Ultegra hydraulic calipers?

[kbike]

I'd use the hose type 1st ment for the caliper.  So if the calipers were designed for bh90 first try those. If you don't like how they feel or the calipers don't move correctly install bh59 hoses.

They're the same as 105. I know this as I swapped the 105 shifters and brakes for the L-Twoo models, and keep the 105 hoses, barbs and olives.

They're finally selling the Ltwoo shifters w/ ZRace hydraulic calipers without the derailleurs. Prices are still a bit high since the full groupset was selling for about $200 alloy and $260 carbon at the last Anniversary sale. Hopefully for the next AliEx sale they should sell for much less. 12 speed still seems to be selling for quite more.

That Alloy R9 lever + XG caliper bundle is the one to get in my eyes

L-TWOO carbon shift levers have a history of breaking and the problem isn't localised to the Hydro, even the Rim brifters have been broken before

The problem comes down to the shifting mechanism requiring way too much force to actuate, with that initial shift being the hardest and getting progressively lighter as you multi-shift. I don't think they'll ever meaningfully revise this so just opt for alloy which should hold up better than carbon blades.

As for the derailleurs, now that you can get just the levers it's a no-brainer to use Shimano. 105 derailleurs are pretty cheap and flawless while the L-TWOO units are fundamentally just slightly improved versions of the original R7. Slapping a carbon cage on it is like putting lipstick on a pig in my eyes, sure it'll be lighter but the function will still be the same. I'll also choose 11s R9 over 12s RX because the 11 speeds doesn't require as tight in tolerances to shift well. For 12 speeds to shift nicely you should use R7100 Hyperglide chain and cassette at a minimum.
