LTWOO ER9 & ERX - Electronic groepsets

[Rebel_Yell]

Looking like there are some price increases on the ERX also Wheeltop EDS TX.   
Anyone else agree?

[raisinberry777]

Definitely - though I expect at the moment part of it is demand outstripping supply for the new v3. Give it some time.

So my er9 RD from 2023 just died after my bike sat on the back of my car through a rainstorm. Me being impatient I orderd an eGr RD from LTWOO official store without thinking more about it. I remember seeing a post about er9 and egr being compatible, but, now I see talk about v1, v2 and v3.Am i ok, or have a just wasted money?

FWIW, I have both v1 and v3 of eR9/X and can confirm they are cross compatible. You are probably okay, assuming eR9 and eGR are indeed compatible. Heck, even GCN video showed their new TT shifter is compatible with the unreleased MTB set. I think LTWOO is making everything cross compatible, which is great for us the customers.

Which seller did you contact? 80 Design Store definitely has V3 and perhaps the best LTwoo aftermarket customer service. 

I can't find V3 on the 80 designer store. Is it on the store right now?

Oh man... so the spring inside the shift lever bumped out and fell out on my ride today.  Anyone know what the size is for the spring is?

You have to ask them, but last I talked to them they are currently shipping V3 groupsets. Just message them to confirm.

In Joe's Shanghai video he shows a bike from Java that has ltwoo blips! I've been waiting.

Let us know what you end up ordering. I would look at the other shifter, estimate the width of the spring, and order random springs on AliExpress and expect to cut them to size. The good news is, it's just a spring.

Installed an ltwoo groupset with ultegra 11 speed di2 calipers. The old ones and can't get it to work, constant disc rub and no place.
Did I mess it up or any experiences here?

Should work. I've done a mix of Ultegra shifters and LTwoo calipers before and I just setup Ultegra shifters with GRX calipers. I'd try resetting the pistons fully by letting out a little bit of mineral oil, install fresh brake pads and use a disc alignment tool if the rotors are slightly off. Following this method has worked for me. In fact I've been able to use 3 different wheelsets on 2 different bikes with no disc rub! So my caliper alignment method has a proven track record!

Works perfect, user error had to restart the bleeding.

Hello everyone.
At the same price (around 700 euros) would you advise me to choose erx 2025 or ali express shimano 105 upgrade kit ?
Thank you

At the same price always choose shimano but ERX should be found a bit cheaper I think.

I am so sorry if this is a newb question but what size bottom bracket is compatible with eRX 2025 groupset? Thanks.
