I had read that the ERX, EGR, and ER9 were interchangeable.
As for the trim, I don't know if it's actually due to the restriction of the ER7 or if it's still a new unit and there are some bugs or maybe some mistake of mine.

EDIT:
I correct what I said yesterday, the trim position is there and works well also in er7, it was my mistake that I didn't understand how to make it work  :-[ :-[

Hi Serge,
I also bought the groupset from 318 Bike Store; I got an ER7.
He also contacted me via WhatsApp. He had my order details and told me his name was Yang.
He only asked me to verify that the order was correct before processing it, and reminded me that I would have to pay customs duties and VAT once the package arrived.
To be safe and out of fear of an AliX data breach (I'm an IT professional and see things like this every day), I contacted support, who told me the phone number belonged to 318 Bike Store.
Personally, I've had a good experience with 3118 Bike Store; they've always answered all my pre- and post-sale questions. I hope they have the same attitude in case of problems.

Thanks for the update on this 318 Store.  Prices are good but could they be trusted and now that is answered.

Yesterday I finally received my eRX.
As I'm located in europe, there was no brake fluid included.
Has anybody used the ezMTB hydraulic mineral oil as brake fluid?
It's the pink one and it's spread all over aliexpress when you search for break fluids...

I already have two bottles at home, but i don't know if I should use it :/

The brake fluid should already be pre-installed in the shifters and brake calipers. I would just connect them and topoff fluid from the hydraulic fluid port on the shifters. No need to do a full bleed.

I just got the cage, but no instructions on how to swap. Do you just undo the bolt that goes through the upper pulley, or is there more to it? Never swapped a rear derailleur cage before.

Sorry, I'm just seeing the post.
I followed this video, which is explained well, step by step.
Be careful when removing the spring with the cage. The spring has a small tooth that must be inserted into the new cage in the same way.

I also live in the EU (Italy), there was no bottle with mineral oil, but both the levers, calipers and cables were already pre-filled

Yes, it would actually be convenient. I don't really like the way ltwoo handles the trim position.

ERX v3 turned up from pandapodium didnt get hit with any fees but the tracking was poor, the site says dpd but it actually got delivered by evri who have a terrible reputation and i wouldnt use for anything expensive. The tracking they gave me is with XDB and still says its at the depot awaiting delivery and doesnt work in evri's system, the guy who delivered it left it behind my bins but he had seen me walking my dog so he returned later on to let me know he where it was if it wasnt for that i wouldnt even know it had been delivered

I massacre the hydraulic cable from LTWOO ER9 when I try put it thru DEDA stem.
Normal hydraulic cable will fit with LTWOO callipers? Or I need LTWOO cable?
Shimano bh59 will be okay?

Any off-the-shelf hydraulic cable and BH59 barb+olive will be fine.

Broke the part where you screw the hose because of too much torque. I have to buy a whole shifter ? 😰

Most likely. It's best to not over tighten the screw nut. I tighten to firmness and leave it at that.

Which oil will be okay for ER9? Shimano mineral oil will be fine?
