I never look at the USB cord light. Just clean the contacts with a cotton swab + alcohol and firmly press on the magnetic charger. Also make sure your batteries were properly charged beforehand. I have an external universal charger that I was able to charge my 14500 batteries before installation.

I've taken my eGR in pouring rain and desert conditions. No problem. If it's problematic, go buy SRAM AXS XPLR or the new Shimano GRX Di2 and call it a day.

Hey thanks for the tip. The alcohol worked. Still a little finnicky, but a 95% improvement.

Hi all,

What's the latest on this issue?

https://youtube.com/shorts/CVCRVtLQP40

Anybody figure out a decent workaround or get any kind of resolution from Ltwoo? Does anybody have any experience or a way to get service from Ltwoo. I'm a bit bent of shape right now because if there's no good way to fix this, it looks like it'll be necessary to uninstall the battery from the bike and find a way to direct charge it everytime. Or replace the derailleur. This particular component doesn't seem user serviceable.

Any help would be much appreciated.

Hi all. This issue was resolved fully with a LBS bedding using the smart bedding machine they have for $40. Money well spent. I'll not try finalizing a brake install myself again. I even tried bedding the brakes myself and got zero improvement. Got the bike back from the shop this morning and the brakes are very nice.

This appears to be user error. There are details in the written Ltwoo instructions that aren't in the video about a push pull procedure. I did it and pulled out huge amounts of air. Haven't tested the bike on road yet, but I thought I'd report back and probably close this thread.

Wrapping up this thread for future users. The VG sports 10-46t 11s cassette worked out well. Very good shifting. I'm not going to bother trying to get that other one to work.

Forgot to mention/admit that I used this mineral oil instead of Ltwoo official

Hi guys, would you take a look at this weak brakes problem I've found after my recent install?



Thanks a lot.

Hey guys, here's where I'm at with this fabulous project.

I'm thinking as the next step, I want to receive the VG sports 10-46t 11s cassette to see what kind of results I can get. Doing so will allow me to zero in on any possible user error contribution. I mean, if the shifting still sucks, and the cassette is within manufacturer specs, the problem may very well be user error.

After that, I may take the bike to the LBS and ask them to see if they can get either the Spedao cassette I am thus far failing with and/or the VG sports cassette to shift well.

And then depending on how those things go, I may try switching the setup to HG hub if possible.

I've asked Trace Velo in a comment on his video where he reported that the eGR is effective on an 11-50t HG cassette, which cassette it is so I can possibly buy it. No reply so far but I'm also sending an email to Luke with the same question and will link him to this thread.

Would you guys be able to help me understand how to possibly convert my XD hub to HG?

I need to first get the XD hub off the wheel and then I think I've found the correct replacement parts. Let me know and thank you!

Is this a 1x or 2x setup ? Also, you said you cannot remove 5 links because the chain cannot be put back together. A link as I understand it is just the outers. 5 links = 5 outers+5 inner plates.

It's a 1x setup. When referring to 5 links, it's based on what's described in the egr instruction manual (attached).

Search for  11-46T 12S cassette in the document to see the chain install recommendation from Ltwoo.

I wouldn't be so hard on yourself. You sound like you might be one single part or even one single step away on your current parts. I think everyone here has hit little roadblocks from time to time. Just be patient and try not to get overwhelmed.

I'll see if I can post a video or photo when I get home and look at my own bike.

Thanks a lot I turn away no encouragements like this!

2 things I noticed:

1) I'm confused as to why 5 links isn't possible for you. Is there something preventing you from using 5?

2) I watched your video. I noticed that the derailleur didn't seem to rotate back at all. I'm not in front of my bike right now, so I can't comment definitively on how mine works, but I'm pretty sure the derailleur rotates slightly on its first mounting arm when torqued properly. Mine happens to not rotate very well, so I have to manually pull it back a little to make enough room and if I overtorque it even a tiny bit it will stay in that position. Which, I believe, is how I leave it because it actually doesn't matter if it stays there. But, if it rotates forward too much or is torqued down and stuck in the forward position, it might not clear.

Hey regarding point 2 on this guidance. I'm not experienced or capable enough to understand this issue and can't see the possible problem you described. I can say that I understand the high and low limiting screws which prevent overshifting outside the available space on the cassette, and I understand the b screw that acts to flatten out and open up the derailleur. The high and low limit screws aren't causing a problem as the setup shifts to the highest and lowest gears, and not beyond. The b screw has been set in various positions, and I can't get smooth shifting past gear 3 onward to 2 and 1 and back again. It's just terrible no matter how I adjust the b screw and per-gear in-app adjustments. The derailleur is mounted securely on the derailleur hanger. Nothing that I'm aware of is bent or damaged. So, I don't know what else I can do.

Here's where I'm at with this phase of the project. It doesn't seem to be viable for someone who isn't Trace Velo or one of you guys to be attempting an implementation outside of the manufacturer's specs, so I'm giving up on that.

Maybe someday I can try again to get this particularly nice 10-50t cassette to work, but for now I'm going to try the VG sports 10-46t item which I ordered from Amazon. I didn't go with the sunrace product mentioned above because it was said that the black one loses its coating, and I don't want an all silver cassette if I can avoid it. So I went with the VG sports product at a much higher price because there's one good review on Amazon for it by a guy who sounds like he knows what he's talking about. Still, I'm probably overpaying at $175.99

Anyway, I'll say this to anyone reading this thread. Don't go with an XD freehub. There's something like 1% availability on cassettes compared with HG.

Lastly, all of this said, I have to admit that I have never in my life been able to get a derailleur to shift well. I've always had to take them to a bike shop. It annoys me, and I always felt powerless about it, and this is a big reason why I wanted e-shifting, so I could dial in the shifting using the per-gear fine adjustment capabilities.

As much as I did NOT plan on doing this, I'm thinking now that it's worth a trip to the local local shop to see if I can persuade them to work on my local shop subverting build and see if they can get this damned gear 2 to shift right.

Yep, I'm thinking I'm going to do that.

Ok, so I couldn't do 5 links because in that config, the chain ends could not be coupled together. Putting the chain ends together with the quick link requires 2 inners. 5 extra links resulted in one inner end and one outer end. So, I had to either knock off the outer, resulting in 4 extra links including the quicklink, or I had to add an inner, resulting in 6 extra links including the quicklink. Hope that makes sense.

Maybe something has gone wrong with my chain due to having added and removed links so many times. But I don't think so. I did see video I think from Park Tools that said if you end up with two chain ends that can't be coupled, you have to take off or add. I can't remember which it was in the video. But either way, I tried both 4 and 6 extra links including the quicklink and got what appeared to be identical results.

More later...

Hey really appreciate this feedback. I'll look into it and reply asap.

Bro you should do your research. ZTTO does sell 9-46/9-50t/10-50t cassettes in 11 and 12 speed. Though as I mentioned their big alloy cogs are not very durable. Also many wheelsets use swappable freehubs. I easily switch back-n-forth with HG/XD freehubs on the same rear wheel. They sell both DT style and 6 pawl freehubs that can be swapped out. Lastly if you had a 15x100 boost front wheel, they sell 12x100mm adapters for like $5 USD. Unless your wheel is 15x110mm, then you'll have an issue! 

I might have to see if my freehub can be changed to HG. I have no idea. It's this wheelset:

https://www.aliexpress.us/item/3256807145194026.html?spm=a2g0o.order_list.order_list_main.5.34221802lfVWiR&gatewayAdapt=glo2usa

So far, I can't find any listing for a ZTTO 10-46t. Let me know if you have a link for one.

In general, I'm finding that XD 10-46t cassettes are really limited. Only found the Sunrace one and this VG sports one, which I'm probably going to try:

https://www.amazon.com/gp/product/B0CLXSMDPV/ref=ox_sc_act_title_1?smid=A1X2Q53T8B3INZ

If I can't get decent performance with either of those, and I can't swap out the XD freehub for an HG one so I can try the many more available HG 11-46t cassettes, I don't know what the heck my next step would be.

I'll look into this front wheel issue more but already ordered a new wheel that's been in production for 3 weeks. Probably can't cancel it. It's this wheelset:

https://www.aliexpress.us/item/3256807145194026.html?spm=a2g0o.order_list.order_list_main.5.34221802lfVWiR&gatewayAdapt=glo2usa

When I couldn't fit the front wheel into my fork, I researched endlessly until concluding that I had made a purchase in error and would simply have to have the wheel rebuilt with a new hub or buy a new wheel. Multiple posts online along with an ai response say you can't change a boost hub to non-boost without rebuilding the wheel due to differences in the lacing length of the spokes from boost to non-boost.

I took the wheel to a local bike shop and asked them for a price on rebuilding the wheel and I provided them with a Goldix non-boost hub to do so. Rebuilding the wheel was going to cost more than a new wheel, and the shop expressed strongly they didn't want to do it and would even make me sign a waiver for riding the wheel because it's not a trusted brand.

Anyway, thanks for the suggestion but I don't understand how implementing an adapter would be viable. Can't find anything like that or any instructions/videos on this kind of swapout. Would be good to know if it is possible though.
