LTWOO ER9 & ERX - Electronic groepsets

[Rajmundx]

Thank you for helping us see the light, understanding that a shimano cassette is free, a shimano chain is free, a shimano crankset is free. You must have done very well in school with that level of intelligence, you should lead the way.

You don’t have to insult people right away — have some manners, man.

I'm updating the situation after some time. Since I installed the battery inside the seatpost with this, I haven't had any more disconnection issues.



I've only been able to use one because I have a D-shaped seatpost.
To "revive" the shifting, I did several tests, and it works both with a mini power bank and with a cell phone + USB-OTG + USBA to USBC.




The day before yesterday, I changed the brake pads and used Shimano L05A ones. To retract the pistons, I removed the screw on the lever side and inserted the cup. Once the pistons were retracted, I removed the cup and closed the system. I didn't have to bleed the system.



I then finally mounted the Shimano 105 11-34 cassette with a CN-HG701 chain. Shifting is perfect. I haven't changed the pulleys yet, as the shifting is excellent even with them. I'm keeping them aside for the future.

Just put my Ltwoo Erx V3 on my bike and it will not wake up if i dont have the charger plugged in
Put everything together on the bench when i got it, tested it, updated it and left it for a week.

Now the bike is almost ready and it will not shift or connect via the app if the charger is not connected.
When connected everything is 100% charged but disconnects as soon as I unplug the charger.

Anyone has och used to have this issue and got a solution?

Hi Jonathan thanks for reply, I forgot to specify that I use 12 speed.
Does the pulley change also work with a 12-speed?

Hi Mashiro,

i have er7 too with 11-32t 12 speed.
i want to upgrade to 11-34t 12 speed, is there any issue? have you tried before?
*with stock cage or need upgrade? please tell me

thanks

I make upgrade from 11-28 to 11-34 without issue with stock cage.
I only adjusted B screw  to move the upper pulley away from the sprocket and re-calibrating. I adjusted the chain accordingly; I probably won't be able to cross 50/34, but that's a combination I'd never use.

I tried it out on Saturday (117km with 3150 + elevation) and I'd say it performed really well.

P.S. For better shifting, I ultimately decided to use the original Shimano cassette, chain, and chainrings.

hi thx for the answers. btw rightnow im using 50-34 chainring.
In your opinion, will it work smoothly? Because the chain tension will automatically increase when shifting to the 34T sprocket, but I might only use the 34T chainring with the 34T sprocket combination for safety.

What chainring size do you use yourself?

Thank you.

I just got called a racist by LT-Ray because I criticized the fact that they keep changing their groupsets. A few months ago I started saving to build a gravel frame and I was interested in building a 2X using eRX eGR mix. Ray sent me a video of the then current wired EGR rear derailleur working perfectly with their wireless MTB Shifters and with eRX Shifters. I was impressed.

Fast forward to today (6 months) and I am ready to buy the parts for the bike as I have saved enough money. I can't do what I wanted because wired EGR isn't a thing anymore and their wireless rear derailleur isn't compatible with the existing semi-wireless parts.

So I criticized them. I said that it shows there is no long term support for the products because if I purchase a part only for it to be discontinued a few months down the line. How am I supposed to get spares? I keep bikes for many years not for months at a time. I want to know a groupset that I am purchasing will be supported long term.

He went off at me! I got told I am not showing respect and that I am having bad attitude. Man respect is earned. You don't just get it for free. A customer is allowed to criticize and voice their dissatisfaction. Nope apparently I'm just a racist.

I guess I won't be buying anything from Ltwoo in the future ever.

when you shift in the rear, front derailleur will move slightly to prevent rubbing. Previously you had to manually click the fd shift button to do it.

[mashiro2004]

This is great news. I immediately tried it on a tripod and it moves around a lot. I think it will consume a little more battery, but it's a feature I like and will use.
