LTWOO ER9 & ERX - Electronic groepsets

[ricedaddy]

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.

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.

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.

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

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

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.

Tires it'd be frame dependent.

Tires it'd be frame dependent.

Of course it is but front mech also plays a role in tire clearance. Most road groupsets can't take more than ~42mm

[jonathanf2]

Tires it'd be frame dependent.

I'd be curious if you could use a hanger extender like a Wolftooth Roadlink? The ERX appears to use a similar shadow style hanger setup now, so it could be possible push the RD to clear an 11-40t if it fits.

I'll be able to report on that towards the end of the year, it's a setup i plan to run with the er9.

Anyone know how far away the ER9 is from being released?

I seem to have read that the maximum rear sprocket for this group is 32 teeth, but some sellers on Ali are packaging it with an 11-34 cassette. Does anyone have any more information or practical experience with this?
