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.

On 80's store's page the description says "2024 new" - does that mean this is an improved version with better water proofing and what not? Anyone bought this recently and want to share observations...there are two buyers on that page asking the same question, without answers.

Answer from 80's :
"Dear ROBERT, the waterproof design has been upgraded, but it is recommended that you still be careful when washing the car, especially not with high pressure water gun to wash, thank you."

My name isn't Robert, so I don't really know what they meant by that haha.

Perfect! So they did upgrade something. May be not to the level of Di2 but a welcome step nevertheless.

You know, everyone talks a lot about the issues with the eR9 and eRX, but I've heard so very, very little about the eGR. I'm guessing they had very little to change and update with a new version. At least, I hope that's the case since I'm an original eGR owner.

I mean, they could redesign some things about it, like increasing the max cassette size (max is currently 48t or 46t, officially, though unofficially it's supposed to fit 50t). They could also tweak software or firmware to add more features that have been requested.

Firmware, yes, but there are a few frustrations I have:

  • Reported charge level is inconsistent
  • The torque settings on the arm to the hanger are completely wrong 12Nm will seize it up, when it is supposed to rotate. The upper one that should be tight, comes loose when torqued to 10Nm as specced
  • The charge port needs a cover, or the centre part should not be recessed, as even the smallest amount of dirt can stop it charging properly and it isn't that easy to clean, needs a cocktail stick or similar
  • It's very easy to get ghost shifts from the levers
  • Range should be 50T not 46T
  • pulley wheel bearings are junk - if they get wet once they're dead, need replacing immediately
  • Stronger magnet needed on charging port

Torque are 10-12 for both on mine, upper is tight, lower is free for me with 12Nm for both.

No ghost shift for me (I have xtar 2.5c batteries)

Pulleys wheels are okay for me but I only did 150km.

Both of my links (upper and lower) are completely tight with ANY amount of torque. (i.e. as soon as the hardware is tightened, there is friction and the link is locked).

I wonder if I'm somehow missing a bushing or a washer or something? But, it's been like that since I first installed it.

Yeah if the lower is free at 12Nm, it sounds like me and you are missing something...
