Tried search the forum for my issue but did not find a solution.

Used my Erx V3 since may with absolutely no issues at all.
Then i got sick and my bike sat for about 4-5 weeks and now the groupset is gone in the ltwoo app.
The app find the RD but its not possible to do anything, so i cant add it again.

Tried emailing Ltwoo but no answer as usual when writlng to them.

Does anyone know about a solution?.

After 5 days i managed to fix my groupset. Still dont know what the problem was. For some reason i could connect to it when i was on my company wifi. So i updated the RD and now it works back home aswell. But it was impossible to do it back home or via 5G on the phone.

So for know its back up and running

Yes, tried with my new one im am going to change to soon. But the same phenomenon.
Can not see it my list, but searching for new ones i can find it but not add it.

location in your smart phone

Yes it is on. Tried with it off and it will not find anything and the app tells me to turn location on.
And I have not changed any settings on the phond since the install of my groupset in may.

you must delete the groupset for app and make new search again
hold the rd image on app. a recycle bin appear . delete it and make new search

My problem is that my groupset is already gone. Somehow its gone missing with out me even opening the app for at least 2.5 months because everything just worked perfectly until now.
So without me doing anything the groupset has vanished from my app. I find it if i do a search but its not possible to do anything. So i can find it but not add it again.

I was going to build my upcoming TT build with Ltwoo since i used the ERX v3 on my roadbike this summer with no issues at all. Loved the groupset!
But now when i did not use the bike for about 4-5 weeks due to sickness and took it inside to my trainer to set it up for the winter the app has lost the groupset and I can not find a way to reconnect it.
And Ltwoo is not answereing emails, so now i am not able to use it after a reset and the shifting only works on about half of the cassette.

So before i find a solution to my problem i can not recommend it.

Have you reset and repaired it?

I have hold the Button in om the RD to reset it. Is there an other way?
But after that i can not pair it anyway.

i was under the impression that external width of rear TT disc wheels isn't as important compared to width of spoked wheels on the front. if you look at some of the leading brands (enve, aerocoach) you will see most of them at 28mm external. because the wind doesn't have to transition over the rim profile, it just moves along the surface of the disc, width isn't as important on the rear disc.

Yes, i have seen that most disc are about 28mm or less outside. But then i saw that Ron wheels and Scope has wider discs.
Thats why i started looking for chinese options.

i can't speak to your first question, but for question 2, the winow arb02 is a direct fit onto the supplied adaptor plate. Its not entirely clean or pretty (the circular carbon extension mounts poke out a bit, unless you want to cut them off). i purchased this adaptor plate and drilled out the hole spacing so it would match the mono riser bolt spacing for a slightly cleaner look.

What is the bolt spacing on the Ican monoriser?
I am about to order one, but looking for options to change the frontend of the bikes directly.

Hi,

Looking for a disc wheel for my upcoming TT build for my and my brother Ironman training.
Does anyone have a recommemdation?
For now it looks like a Serenade TRW80s in front with 23 inner and 31 outer width.

But its harder to find a disc closer to that width.
Carbonal DR-W30.5 with 23 inner and 30.5 outer is the only conteder so far.

Just wanted to add my Echo build.
Spent about 1200km on it now and love the feel of the bike.
Its built with Ltwoo Erx, Shimano Dura-ace chain, ultegra cassette and the wheels are a mix of Sernenade wavy rims and goldix hubs. Then i use the magene teo 170mm crankset with powermeter.

After some hurdles with the buildup it has been really smooth.

Upgrades to come are 20mm longer stem to change my position a little bit and the wheels will be changed to a set of Zen wheels. Just should decied of what.

I'm experiencing the same issue you had, thought i'd splurge on a pair of 1500mah Keepower 14500 for a massive range upgrade but seems like LTwoo doesn't like that even though the current is the same... Welp will order a pair of 800mah batteries und hope for the best

I bought Keepower 14500 800mAh and they seem to work really well. Did Vätternrundan (315km) with my Ltwoo setup this weekend with no issues at all.

What batteries do you use? Ive had aimilar issues when i tried using 1000mah instead of 800

Ordered another set of 800 batteries and now it works. So something must have been or gone wrong with my first set of noname batteries.
Bought a set of Keeppower 14500 batteries and now it works fine. Just did a 150km race this weekend and yesterday 90km of training with no issues what so ever.
