Yes, the jockey wheels. I was able to remove the wheel from the frame, but the bearing inside of the wheel was a closed, cartridge bearing. The bearing was rough, not just the wheel in the frame. Despite being a closed cartridge, I held my grease dispenser right up against the seal and managed to squeeze a tiny bit through the gaps. I could even see some watery/yucky discharge ooze out the other side. After that, it rolled much more smoothly. I can't imagine it's going to hold up very well for long, though. This was only for one wheel, the other seemed to be perfectly fine.

The good news is that jockey wheels are generally pretty interchangeable. You should be able to find a replacement without going back to LTWOO (Half of my bikes have non-OEM jockey wheels anyway because they look cool :-) )

Yeah, I think that's a big failure on LTwoo's part. My ER9 groupsets are working solid and I would probably get an EGR as well, but I definitely wouldn't recommend them to anyone who isn't bike competent. Also it seems 80 Design Store seems like the only seller that's taking personal responsibility for any issues. It's a shame too, because LTwoo whittled away being a viable alternative to the big brands by not offering a clear customer service path. I think reputation wise, they've taken a big hit internationally.

They should take a similar approach to Wheeltop. They could sell direct and say they will handle warranty issues only for groupsets bought from them. They can still have third party sellers who could sell groupsets at a lower cost, but those sellers would be responsible for covering warranty issues.

 

Good observation and recommendation. I'm rooting for LTWOO here. They clearly have at least a "good enough" first try with the electronic groupsets. And possibly better (verdict still pending IMO). The price/performance point they are hitting blows away the big three (well, sadly 2. something since Campy is a bit of an outlier lately) and will hopefully provide some downward pressure on pricing. But, if they don't get their go-to-market strategy and execution together, it won't help at all.

I've been happy so far with the eGR I put on my Cutthroat this Spring. But if you can source GRX Di2 or SRAM AXS for similar pricing, go with that. They are a known quantity with local support. But when I last looked, those were still double (or more) the price so it was worth the punt. AND because mine was a retrofit on an 11s system with two existing wheelsets and cassettes, the total upgrade cost would have been substantially more. (Shame on Both 'Big S' companies for not offering configurable 'speeds' with electronic. No excuses, just greedy business to force full upgrades) All the Chinese e-shift vendors have realized there is a market for configurable shift setups.

If the question is mechanical from mainline brand or LTWOO eGR, that's more complicated. Mechanical works. Usually :-)  Shift setup and maintenance in an offroad environment can be a bit fiddly in my experience where electronic is set and forget (except for RD hangers). The biomechanics are also nicer on electronic. I've never ridden an 10s or higher setup that wasn't straight from an adjustment work perfectly. Always a little finesse to get some gears to engage perfectly. Not a big deal, particularly for someone who started riding before indexing. But it does lead to reduced shifting to avoid the hassle. With e-shifting (I have eGR and an AXS setup on two different bikes) it just works, always and I find myself not hesitating to snick one up or down for a moment. But that's me. YMMV. Also, if you have any hand or wrist issues, e-shift is a savior. I had a messed up wrist a while back and could barely work the front derailleur for a while. Wouldn't have been an issue with e-shift. These are decisions you need to make for your taste.

Does LTwoo eGR show up in bicycle computers (wahoo for example) like Wheeltop EDS TX ? To see battery level and shift number ?

Yes and no. I have used it on Garmin Edge 1030+ and 1040 and a Karoo 2.  On all the gear setting report seems correct (there is a small latency but that might be normal for all eshift systems). But battery status is an issue on the Garmins. Even when full they throw an alert that battery level is critical. So no useful information there. The Karoo reports a status of full but I don't know if it updates correctly (it is a spare unit I just connected to answer this question)

It was purchased on March 12th. I'm not sure when in it was made but was from official store so hopefully wasn't old stock, but you never know.

Honestly, that's a little worrying (as a fellow owner purchased in May). I'd thought they might have purged that issue much earlier in the year based on the threads online.

For whatever it might be worth, I've been allowing a hose (not a pressure washer) to hit mine and so far so good. (not likely to rain here until October)

Has anyone tried the rear egr mech with the erx grifters to see if they pair? I want greater capacity in a 2x system

I have not tried myself, but I saw on some show video recently that LTWOO claims cross-compatibility with all 'e' systems of theirs.  I have had good luck getting response from LTWOO 'sales' email (sales @ ltwoo . com), you might just ask directly

Can anyone recommend a good ali 1x crankset that would marry well with the eGR groupset?

Also - I've read in this thread about replacing the calipers with something like the ZRACE XG flat mounts. Is this necessary or will the adaptors that come with it suit a flat mount gravel frame?

Thanks!

The calipers WITH PROVIDED ADAPTERS should fit flat mount. I cannot confirm 100% as I'd been told they'd fit my post mount (they do not). But they look right for flat mount.  It's worth noting that the caliper itself does not and fits no standard I know of (room for things I've missed), but the adapter is provided to make work. 

I have more detail here: https://trbike.blogspot.com/2024/05/ltwoo-egr-results-writeup.html

...I would suggest checking the 3 T10 screws that face towards the floor. During my setup one fell to the floor. I added some blue thread locker and snugged all three. Unsure of a torque spec but the seems like they would strip threads easy so take it easy if you do this.

Andrew, can you clarify which screws you're referring to? (picture maybe?)
