LTWOO eGR

[Shin56]

From the looks of it the new version finally swapped to carbon fiber shifters(according to the website it was only aluminium before), although it's dissapointing to see that the left shifter lost it's buttons so there is now no hope for letting us assign shifting to two levers at once.

The ergonomics for shifters are now exactly the same as newest golden eRX version and it looks like rubber and shape got updates, it seems they are slightly longer and have gentler angle to them now, lever shape is also changed.

The brakes seem to be the same ones that started shipping at the start of 2026 and just slightly updated V3 version that do not need adapters to mount.

Now the most exciting for sure is the RD, finally we have a full wireless system and it seems they optimized the weight a bit since it claims to be the same 333g as previous version(info from the website) despite now having a battery included(overall the groupset is lighter by the weight of battery pack, cable and batteries). But the rated capacity of 400mAh is concerning, previously the battery pack came with two 800mAh for a total of 1600mAh and while LTWOO claimed 3000km range, based on posts on this forum realistically it was way lower. Now they claim 1500km range with 400mAh so unless they made some massive improvements to current consumption of their RD, range might be a real problem with the new version. USB-C charging is the second best change right after full wireless imo and very very welcome one. Now the RD officially supports up to 50T cassette but the cage design does not seem to be different so it might just be updated spec sheet instead of any real change but will need to be verified once they ship the product. Also integrated battery is not ideal but as someone else mentioned it's mostly due to SRAM patents, but it will be sad not having the option to just swap the cells or upgrade them to higher capacity sometimes down the line.

I hope price will also go down a bit since now only one shifter requires electronics and all the HW, while the other is just a brake so hopefully it can bring the cost down even further. I hope they also release 2x12 version since the shifter is direct copy of eRX now so should not require much R&D there and only require new FD design(hopefully finally fully wireless FD as well and maybe full wireless eRX in the future?).

Lastly their product refreshes and naming scheme is super confusing, they have at this point like 6 different versions of their eGR product and no database with spec sheet for older generations, their manual is also very outdated alongside their instructions videos. Hopefully they update the older generations to 13s as well but it might be just hopeful thinking since they got 2 different models at the moment on their website, one for 10-12s and the other for 10-13s and there might be HW differences between the two.

Overall new refresh seems very interesting and step in the right direction but imo the first generation of this refreshed product might not be as refined and need improvment. Still the most concerning part is the battery capacity of RD, and removal of control buttons from left shifter.

Just recieved a new eGR groupset, ordered it around 4 weeks ago. I had to pay around 350$ for the groupset and additional 35$ as tax and import fees, it spent 3 weeks of it's journey sitting in different import offices but thnakfully i did not have to pay the full amount of tax + vat. I will share some of my first impressions and thoughts about it and some pictures.

First of all it looks very good in person, I did not expect it to look this premium, shifters and RD are very nice and felt good quality, especially for that price, brakes look amazing as well. Battery pack and cables is where Ltwoo lost some points from me, battery pack is extreamly flimsy and cables themsevles do not feel very durable imo, especially with the need to unplug one to recharge(yes I still recieved the old version but in gold colour, not the full wireless).

When trying to setup and test the groupset ofc the link to android app on their website does not work and forces user to find it via google play store, instructions are very outdated as well, and app itself while ok, it could use some work and improvements(Iw would not accept my password despite fulfilling all conditions and required reinstall). Afterwards mounting CR2032 batteries in shifters was horrible, rubber was very hard to pull back and replacing the batteries will be even more of a pain(at least rubber will get slightly worn out and might be easier to pull off). I also purchased the wrong 14500 batteries as i got ones with flat top, but LTWOO requires button style ones, I ordered some neodymium magnets to work around the issue as i got F15 Vapcells that have 1500mAh capacity each and it would be too expensive to just ordered another ones, and contact resistance in this wattage should not make much of a difference so for anyone else 5x1mm neodymium magnets should work as top button replacement for this application.

Now I have not been able to test much more and just checked the weight of entire groupset atm as im still waiting for my lightcarbon LCG074-D frame to build an entire mostly aliexpress gravel bike, but hopefully in around a month I can come back and give some more of my thoughts about this group.

I have recieved the V3 version, but with updated shifters and letter coloring to gold ones, seemingly its a transition version of between full wireless that was recently announced and old V3 or blue version. I attached some pictures for the weight and how the groupset looks with updated visuals.(First time attaching a picture to a comment so it might not be ideal)

What store did you order through? Did you retain the buttons on the left shifter or the new set that dropped the shifters?

I order via 80s desginer store, initially they send me a picture of a blue version of shifters but i recieved the golden ones. They both still have all the buttons just updated letter colour and rubber design. Overall what i got is just a redesign of a blue version.

At this point, I'd just wait for the upcoming full wireless 13 speed eGR groupset to drop. I don't like the idea of having to unplug the battery cable and use a proprietary usb cable to charge it.

Yeah i wish i had waited a bit more but i ordered my set around a week before new full wireless got announced. I could just refuse my package, but seeing that we do not know when it will go for sale, what price it will be etc. I decided to just stay with old design. But as I stated in my other comment, while i think that 13 speed and full wireless is nice I do see some drawbacks from new design as well.

Let's start from the positives:

- 13-speed, obviously it's great having an option to go up to 13 gears, but atm 13 speed cassettes are quite expensive and there is also a weight drawback, so while nice options ot have imo its not really essential.
- Full wireless is great, no flimsy cables or battery pack, but it has drawbacks i will discuss later.
- Seemingly much more robust B screw bracket and metal piece(yes the one that snapped in blue version for trace velo).
- RD of the same weight even when it has battery attached now(overall system around 80-100g lighter)
- USB-C charging, no flimsy proprietary charging cable.
- Possibly cheaper due to less components(no left shifter buttons, no cables or battery pack)

For drawbacks
- First generation of full wireless, might have some hidden troubles that did not get caught by Ltwoo, like many of their other first gens.
- 400mAh battery capacity. Previously we had around 1600mAh in the seatpost pack that Ltwoo claimed lasted 3000km, but many user claimed less. Still had an option of putting vapcell F15 in there for example and get total of 3000mAh capacity(7,5 times what full wireless has).
- No shifter buttons on left lever
- No swappable battery

I think overall its a step in a good direction, but at the same time at one point i was thinking I could try to use er9 FD. No Idea if it will work yet, as there is not a lot of information but it would be pretty cool if it's a viable option. I would need new battery pack and cable but i could have USB-C charging and an option to go 2x. And replacement cables are still like 20$ so I think i'm going to order them just in case they become unavailable later down the line. But still my main reason is battery capacity and possibility of maybe creating 2x system as i live in pretty flat place. The only reason i did not go for eRX is becouse I still enjoy riding forest or dirt roads the most.

Overall, I wish i knew they will refresh eGR a week after i ordered, but at the same time I don't think it would change my decision.

Gave my bike with eGR a quick, gentle wash and now the rear mech is dead. Hopefully just airing it out will solve the issue as it did in the Trace Velo video. Will definitely do the waterproofing as others have done moving forward.

Was your cable plug fully seated into the RD? I've ridden my eGR equipped gravel bike in several rainstorms with no issue. When I get home I always dry my bike and sometimes use a leaf blower. I dry more to protect the bearings and to avoid any sitting water.

[00Garza]

Pretty sure it was. Then again, I’m also scared of damaging the pins when plugging it in, so maybe not.

[00Garza]

After letting it sit unplugged overnight it’s alive again, but batteries are drained. I’ll give it a charge and see how it’s doing later.

[00Garza]

New problem.

Left it charging and when I came back to check it out it’s unresponsive. Light on rd is constantly blinking. Also, no green light on shifters and they are unresponsive. Is it possible rd stayed active and somehow drained shifter batteries?


I can see the mech in the app. When I do the long press on mech button, it resets in the app but the cage does not move.

Honestly, this is more or less how 3 of my RD died. I am on my 4th now which does not have the magnetic charger anymore, so far so good. It always started with a light wash, the RD being unresponsive after, sometimes it came back to life but then started draining batteries or misbehaving in other ways until it fully died. That's the negative. Lucky for me, each RD died within a year of purchase or replacement so the shop I bought from (80s designer store) has been extremely helpful and replaced it each time. I just had to upload proof in form of videos or images and pay for shipping. That's the positive. That being said, my wife's eGR is still going strong after 3 years. Maybe it's me.

Unfortunately its been over a year.
Double checked the app and it does show the shifters still working and the moving the mech, but the mech is just not responsive. Green light shows up though.
I also bought from 80 designer store. Messaged them yesterday and hoping for some help from them, but might end up having to buy a new one. 

EDIT:
80 Designer store replied. Old mech is discontinued. Waiting to see if they can get me the updated one individually.

I hate that LTwoo removed magnetic charging. All they needed to do is put a rubber gasket on that stupid charging port. My Wheeltop GeX has a rubber cover and that mech works fine in wet conditions. Though Wheeltop brake levers ergos are such cr@p and shifting is less responsive compared to LTwoo.

For all the quirks of eGR, when it works, it's just as good as my friend's 12 speed GRX Di2 and the hoods and lever positioning is perfectly suited for fast downhill riding.

Hard reset the mech like 10-20 times and have it plugged into the charger. I revived a dead ER9 RD that way and since then haven't had issues. I even sent a video to 80 Design Store, they sent me a replacement, but I revived the RD so I ended up with a spare!
