LTWOO ER9 & ERX - Electronic groepsets

[TidyDinosaur]

PSA: Please please please don't buy this groupset if you're price conscious and can't afford to write the purchase off. This is not the product for someone who simply wants something that 'just works' and can't stomach the pain when something goes wrong. The software is barely 1st gen, as is the hardware and everything is subject to change in later revisions/generations. I'm excited in the eRX because the underlying foundation could truly shake up the industry but evidently there is still much to improve.

By the way, zero proper reviews exist on the Chinese side of the internet as everyone there is waiting for someone else to take the risk. Just this week someone posted about aftermarket DM hanger clearance issues. Again, don't be a guinea pig.

Well said. We're no longer talking about a 150 € groupset like the Sensah stuff a few years back. If it did not work, it was a small price to pay and you moved on (I was in that situation). But the price of these new groupsets is just too much to gamble with...

One of the first builds I've seen with it

Almost same situation in EU. SRAM Rival is at same price than LTWOO, and Force a little bit higher. For me, no cost/risk option going for LTWOO, and at it first batch.

I don't know if it is because I'm searching from Denmark but I can't seem to find either 105 di2 or Rival eTap AXS for nearly as little as you seem to be able to. Can you or someone else perhaps provide a link or just a site name for deals with either of the two here in the EU?
The best deals I've found so far are:
Full 105 di2 for 1150€ on bike-discount.de.
Full Rival eTap AXS (excl. rotors and BB) for 1260€ on bike-components.de

You got the ER9 comparable groupset for EUR 780.
You can add Cassette for 100, Chain for 25 and crankset for 90, rotors for 80 and got the full system for less than you found.

The retail price for the er9 is under 500 USD without shipping. They will start selling them in the coming weeks I'm told. Should mean 600 shipped to most jurisdictions at most. I plan to buy several in the coming weeks.

Sounds like Ltwoo is getting there. If panda podium starts selling the set, then I think that's a pretty good endorsement. That being said, the price seems bit too high still for me.

[Takiyaki]

Its really interesting to view this in terms of the market. For all the places Chinese brands have been able to make inroads it's interesting that folks draw the line here. Basically if it's something that will need continued support and development.... no thanks. Heck even a mechanical Chinese groupset might not be worth it to someone who has a bike shop do their work. They might not touch it. Definitely some things to think about.

youtube channel tracevelo put out a review of the groupset over the weekend. 

[jonathanf2]

I might skip the ERX, but I do like the idea of the ER9 1x setup. Plus going LTwoo electronic solves my issue with LTwoo mechanical and it's the terrible ergonomics with the thumb shifters. I also like the change to the shadow style rear derailleur (hopefully the ER9 does the same) and the replaceable rechargeable batteries. If anything, I think there's a proven track record with Chinese manufactured electronics. Going electronic would probably be more reliable than staying mechanical in the long run.

Have they said whether the eRX has satellite ports? I’m guessing no. Maybe for the second gen. For me, that’s one of the huge benefits of electronic shifting. And a prerequisite for me to upgrade at this point.

I second that. If electronic shifting didn't have the advantage of being able to have the satellite shifters I'd just go for much cheaper mechanical. If you're a racer it's super nice to have them in the sprints.

Looks like there is a manual trim mode following removal of the auto-trim:

Also this user reports no issues with sleep mode after 2 weeks, so it seems that issue may be fixed too.

[kbernstein]

Has anyone tested clearance for gravel in both tires and cassettes?

Does it take a 11-40? 11-42?  45mm tire?

[vuldr]

Took a gamble on this groupset and it's been stellar. Rode around 200 miles so far on the 11s settings and everything has been crisp. Only issue I had were some cosmetic blemishes on the rear derailleur near one of the screws.
