LTWOO ER9 & ERX - Electronic groepsets

[biceryder]

Funny, I just purchased that exact 105 groupset.  With taxes and shipping it was 720.00.  Shipped to my house via DHL in one week.  Consider me impressed.

Seems a lot of the sellers exclude the battery, only include the battery casing. Searched through LTWOO's site and manual but no mention of what battery types the battery case accepts. Anyone know?

Any type 14500 batteries. 3,7v and 800mAh. Available anywhere at about 5 EUR a piece.
Make sure that the +pole is not flat, there are two options for that. The raised pole is what you want.

Also make sure the battery is exactly 50mm. I've picked up 14500 3.7v 800mah batteries that were 51mm-53mm and they're too big. 51mm will barely fit, but I didn't feel comfortable because it put strain on the battery holder casing.

This is often called "button top". You want button top 14500 cells. And, you also want to make sure to get some without extra fancy features. Some offer special USB ports for charging the cell via usb or other things like that. You don't want any of that, and it might interfere with how the Ltwoo charger is supposed to work.

80 Design Store told me they're selling the new V3 ERX as a complete set for now (using the old link). Compared to Panda Podium pricing, it's still cheaper to buy from 80 Design Store and their warranty service has been excellent so far. Though above $500 USD there is also Wheeltop EDS TX and 105 Di2 to consider. Wheeltop and 105 Di2 also allow larger in-spec cassette range. It's nice to have more options!

According to 80 designer store everything can be mixed and will work together. Good news for broken RD's! But they aren't selling them seperately.

I bought a ER9 RD at 80 designer store 4 weeks ago. 151 Euros.

Did you buy an ER9 groupset from 80 Design Store? If you had issues with your RD, they will send you a warranty replacement (just pay shipping fee).

He said RD only. 151 euros for the whole groupset would be a steal!

For reference, i could pull the trigger on this group (no cassette) for 630 eur, and i'd expect to pay customs fees (<100 eur?). With the new ERX costing 650$ on Panda podium, the price difference is arguably in favour of shimano, because if you buy ltwoo, you "have" to budget a spare RD. All the bikes i've installed ER9 on have had a RD die.
Note: i just bought another bike for a friend in parts. Aliexpress is becoming very confusing. Prices are much higher than over the summer (10-20% higher), and there's now a lot of volatility over time (if you buy stuff when there is no sales campaign, prices are often much higher, so you really need to time your purchases, even if you forget to use the coupons, and depending on where you ship in europe, prices are increasingly diverging. And there's quality fade i can point to specifically.
Also, as of 2 days ago, it was impossible for me to buy an er9 group on alix, they wouldnt ship it, claiming issue with the 150 eur EU rule. Problem being, you can buy wheels on alix and other stuff that's way above that 150 threshold, so, go figure the logic.
Everything ltwoo also has prices jacked the F up in the last weeks. I used to pay 150 eur for a spare RD, now if i find one that can be shipped, it's much more.
Very confusing stuff, and i'm the highest tier there is on aliexpress, so i know my way around the platform quite well.

I didn't think it was just my imagination that the Chinese electronic group sets had jumped on price the last week or so, damn.

What is the best value set right now for just the levers, disc brake calipers and cables plus derailleurs?

80 Design Store got back to me. They are officially selling both the new V3 ERX and ER9 groupsets. They haven't updated their profile description though. I did ask if the V3 ER9 has the new FD charging port. There doesn't seem to be much info about it, since all the influencers are pushing the ERX as the only option. From my experience with the eGR, I really do like the newer tactile shift buttons and the mono block alloy calipers have more bite than the older calipers. Though I would ask beforehand before ordering to specifically received the 2025 V3 groupset.

The cheapest spot to buy LTwoo groupsets is from the LTwoo official choice store. Just make note, The LTwoo official store won't warranty coverage the items. I did risk buying my Ltwoo eGR groupset from that choice store since it was under $300 USD, but I knew what I was getting into and the savings was worth it to me.

AliEx always have these price fluctuations. Best bet is to add an item on your wish list and monitor pricing. Also I always double check Super Deals on AliEx, because sometimes the same item from the same vendor will be cheaper if buying it as a Super Deal item.

I wouldn't be surprised if there were some prices drops between the spring and summer sales.

Feels to me like everything jumped in price tbh. Even shimano groups on ali jumped like 10%

Two er9 sets here without issues, not the early models. Paid 344 dollar with coupons for the last one. Declared lower value and 36 euro import costs.
