LTWOO ER9 & ERX - Electronic groepsets

[SillyMochi]

I would have liked to have gotten it from 80s Designer Store, but I couldn't find it and I wondered if they had sold out.

I was looking for it a few days ago as well and couldn't find a listing. Seems like they don't offer it right now. No idea why though. This is the old listing which shows it as "no longer available": https://vi.aliexpress.com/item/1005005922459020.html

Been speaking directly with 80 Designer Store over the last week or so and sounds like they are sold out of the new version ER9 which would have been my preferred option.

But I have just picked up an ERx groupset from them for £408 (with some vouchers). The listing had photos of the OG version but they confirmed through photographs that it will be the V3.

Excited for it but finding the very limited online coverage of it a bit odd.

Will post some shots once it arrives.

I spoke tu 80 designer store and he said he will have stock again for er9 in April. I am also in Canada and want to buy a v3 er9. If anyone has lead to buy one at a good price...

Hmmm... I thought for sure I had bought it from Ltwoo-official store, but you might be right and it was a choice purchase in actuality. Thanks for pointing that out, and I'll be sure to keep that in mind when I receive it (especially since I don't plan on using it right away).

Update us when you get your ER9 groupset and which version you get. If it's not V3, returning Choice items is fairly easy.

I double-checked, and - though it was a choice purchase - the seller was actually Ltwoo-Official store. So, I assume I'll be able to reach out to them for after-sales support in the event of potential warranty issues. They may not have the stellar track record of 80's Designer Store, but I don't think I've heard any horror stories either. Furthermore, I know for a fact I can reach out to 80's Designer Store for buying spare parts, should I end up having to buy something that breaks on it.

Have it now for over a year , you can't expect to be competitive to Shimano or SRAM for this price but it's just garbage.
 I can only use it in summer because when it's below 12 degrees or raining it stops working. Through the app it still works but shifter compared to derailleurs don't do anything.
When i am home , after 5 minutes inside, he works again.
No big loss for the price you pay, but i would not do it again. Just buy some mechanical Shimano instead of the price.

Bad news, gents. I just received my eR9 from the choice purchase and it is NOT the new version. Definitely the old version with the magnetic charging on the rear and the old FD without USB-C charging. Oh well. It was still a great price. Now I gotta think about whether I want to keep it or deal with a return.

I got the last ERX listed on the LTWOO factory store for now. They said it is the V3, the FD has USB-C but the rear derauiler also has the magnetic charging. I asked a few times if the RD is infact V3 as well and they reassured me that it was.

I guess we shall see

I'll look again when I get home, but I did not see either the USB-C port nor the open area to adjust the FD location that Trace Velo pointed out.

Oh I was just mentioning what I am anticipating from LTWOO, they sent me pictures of the groupset so I could see the FD has USB C etc

Been riding with this in rain and freezing weather. Just works here. Only thing I had a few times was ghost shift on FD on one of my three er9 bikes.

Have you done any of the "weather sealing hacks" to your group? Like the silicon grease or other "insulation" works that had been suggested on this thread?

[jonathanf2]

It's also been almost a year running ER9 on two bikes as well (using dielectric grease and sealing the plugs with rubber cement glue). So far they've been working fine. I had a few battery related bugs, but those issues have been ironed out. My only other issue is that my FD cages are showing heavy brassing. Unlike Shimano, LTwoo doesn't provide skid plates. In comparison my Shimano FD cages look immaculate even after heavy use.

Well, after seing seraph selling fully built carbon bikes with complete wheeltop groupsets for 899USD fob....you can imagine the margin...i suppose, the prices will drop massivly pretty soon....

I've had that, too. But other than the surface finish wearing away where the chain rubs, is that really an issue? It's really only cosmetic, I suppose. I didn't have the impression that the chain would wear through the FD cage.
