LTWOO eGR

[amacal1]

Aside from backpacking I don't think many people are carrying a power bank around with them...

I mean, not on the bike. But a lot of people carry them around when traveling. For the Ltwoo eGR, it doesn't take that long to get some charge in the batteries and a little charge seems to go a long way. If you're that low, 20-30 min on the charger is probably enough to get you through most any reasonable ride, I would think. Before you ride, pull out your power bank and pop it on there, then go fill your water bottles, eat a banana, check your tire pressure, etc. That's not even wasted time.

If you've got a much longer or more challenging ride, just take a little longer, idk.

Curious what size jockey wheels are used on the EGR? Goldix have a few steel bearing jockey wheels and LTwoo seems to use off-the-shelf parts when possible. Would any of these match?

I finally got around to replacing my gritty jockey wheel last night. I had bought a super cheap aluminum ZTTO branded 13T ball bearing jockey wheel as part of a choice purchase on Ali for less than $2. I was worried it might be too big, but it actually turned out to be smaller than the original. I believe I counted 14t on the Ltwoo wheel. So, close enough to not be an issue. I'm not sure if 15T would fit, but I would think anything 16T or bigger would likely be too big.

13T was fine and the jockey wheel worked for now. I'm afraid that this bearing wasn't sealed, either, and will suffer the same fate as the original once I hit some water and mud. At that point, I'll just replace the bearing since I'm pretty confident I can pop a new one in and out of the wheel and will likely go ahead and do that to the stock one now that I have it out.

I replaced the bottom jockey wheel. Has anyone replaced the top jockey wheel, or even removed it? I can't seem to remove mine. The hardware for the arm is not backing out. I didn't investigate further, but it almost looked like it wasn't designed to simply "unscrew".

Hi, someone maybe have info if shiffters from EGR work with RD from erx/er9 or shiffters from er9 with RD from EGR?

Some people have both groupsets, but no one has taken the time to try it. You wouldn't even need to remove the groupset from either bike, you just need to hold the ER9/EGR RD button and shifter button and see if they'll link up.

I've got the problem where I can't charge it, AGAIN 

OK, resolved. I had to find a wall unit with 5v 2A+, and then use a cocktail stick to clean the central contact point of the charging point on the RD. Now I am getting a charge. That port really needs a cover.

Yeah, I've had that problem before. Maybe not that extreme, but at least once I thought it was happily charging for hours and then said it was done, only to discover it only had a couple of percent more than when it started.

I've gotten in the habit of giving the port a little wipe with my finger right before I drop the mag plug on it. Seems to be working pretty reliably so far and is easy.

Just place a small strip of electrical tape. That should protect it.

Honestly, I'd be just as worried about residue from the electrical tape. You just gotta give it a good wipe before you plop the charger plug down. At least with mud/dirt/dust I can wipe it off, but with ultra sticky tape residue, you'd have to give it a good alcohol rub or something.

Someone had a problem with charging cable ? Mine doesn’t function anymore. It seems to be electronics because when I plug it into an USB power bank, the power bank seems to shut down immediately.

I used two sockets and a bench vise and they popped out pretty smoothly. One the same size as the bearing and the other large enough to support the jockey wheel and allow the hearing to pass into. You could make a drift with a bolt and washer and use a socket on the other side for the bearing to pull into.

Take care when pressing the new ones in to make sure they are even. My first attempt the bearing was a bit skewed so I had to remove and redo.

I tried to knock a seized bearing out and the pulley wheel snapped in two. Ah well. Plenty of cheap replacements with better bearings. This groupset is off to the winter bike. Too many problems. Wheeltop GEX on the way for the gravel bike.

Lots of people report issues charging when there is some debris or residue on the charging contacts on the rear derailleur. I've had it fail to charge or report fully charged when it's not. You could try to wipe those thoroughly and see if that helps.

If you're sure it's the charger cable, you can order an extra one.
