Re: LTWOO ER9 & ERX - Electronic groepsets
Hiall. With regard to the RD connector, I have sealed this with heat shrink tubing. Let’s see how this works. This is my 3rd RD. Works as a charm again. Hopefully three is the lucky number.

Re: LTWOO ER9 & ERX - Electronic groepsets
finally pulled the trigger yesterday. 330€ without maybe customs was too temting. Has anyone replaced the breakpads by now and can say, if there is a shimano alternertive? and if yes which model does fit? I paired my eR9 with ZRace XG caliper and Cooma Elite pads (the pink ones). I am just impressed with the Cooma pads. For the price, it has no business being so good and I have used all different kinds of Shimano pads before. I can comfortably say they are almost as good as Shimano's. Please note that I weight somewhere between 68-70kg, depending on the days, so that may change the results. Also impressed with the very minimal disc squealing noise. March 19, 2024, 09:32:08 PM |

Re: LTWOO ER9 & ERX - Electronic groepsets
Thats me and nope no solution yet. Just for saftey reasons that i by mistake shift both exactly at the same time i put my charging cable and a usb-a to ubs-c adapter in my saddlebag, so i can connect the rd to my phone as a charging device and get it working again. you run 2x11 or 12? Yestrerday I was testing and with gear protection off my system go down after only one change from 1 to 2 at front, with gear protection on this situation happend less often. I think this is connected with some adjusment of FD, when shift on front is smooth then is ok, when not system is blocking. I'm in contact with Ltwoo and Store from aliexpress ,but damn, they are silent ;/ Support even not exist Could somone whith 53-36 on front take photo of FD when is at second gear ( now mine is set with sticker 3mm up the tooth) and screen with calibration for FD on 1 and 2 gear (i know that this depends which frame, hanger etc.) //Edit: I have contact with a few people with Ltwoo and I have tommorow video call or chat with someone from tech support, will see May 16, 2024, 05:59:46 AM |

Re: LTWOO ER9 & ERX - Electronic groepsets
eR9 issue and fix I had an issue with my L-TWOO eR9 groupset today that I later fixed. It was most likely user error, and I'm posting it here in case it could help someone else in the same situation. tl;dr Problem: The front derailleur wouldn't shift, but the rear derailleur shifted just fine. Fix: Ensure both derailleurs are firmly plugged into the battery, by unplugging them at the battery end, and firmly plugging them back in. Likely reason: Poor connection to the seatpost battery on the battery end, possibly caused by vibrations by being transported in a car. Other plausible reason: Dodgy batteries. Situation I was going for a ride in the morning, and I loaded my bike (https://chinertown.com/index.php/topic,4952.0.html) in the boot (trunk for those of you in the US) of my sedan (saloon for those of you in the UK), lying on the side (NDS). The drive to the start of the ride took about 20 minutes. When I took my bike out of the car, the rear derailleur shifted just fine, but the front derailleur wouldn't budge. I tried the following:
The only response I got from the front derailleur was when I plugged the front derailleur cable back in. It was a buzz reminiscent of Trace Velo's issue (https://youtu.be/32UDzOrqK2I?t=78s). Other behaviour I noticed:
Other points of note:
At this point I thought the rear derailleur was toast (which apparently was Trace Velo's problem in the end), but I decided to do a short solo ride anyway, with the front stuck in the small chainring. After riding for about 50 meters, I tried to change to the large chainring, and it shifted! Actually, it over-shifted, because I had lost my position settings when I "Reset to factory settings". So I stopped, put the chain back on, and tried to shift down. No response. The rear still shifted just fine. I then proceeded to try many of the steps listed above one more time, but no luck. So I started riding again, and after another 50 meters of so, I could shift back to the small chainring. That was the last time the front derailleur shifted until I got back home, so put my rear derailleur position adjustments back as they were and did the ride in the small chainring. It was fairly hilly, so I could at least get up the hills! After I got back home, the front still wouldn't shift. At that point, I wanted to check the connections on the battery end. So I pulled out the seatpost carefully, as I wanted to see what state the connections were. But as I pulled the seatpost slowly and carefully up and out, both derailleur cables came loose from the battery case connectors. I then plugged both of the cables into the battery holder, and immediate success! I could shift up or down without issue as before, and the front derailleur firmware now showed the correct version. My main hypothesis is that I didn't plug the cables properly into the battery, and that the vibrations from being transported in a care shook them loose. Then when I started riding, the movement caused just enough of a connection to be established so I could shift. Assuming that's the cause, does anyone have suggestions for how to better secure the cables at the battery end? Another hypothesis is that the issue was caused by dodgy batteries in the battery holder. I don't have anything to support this hypothesis currently, apart from the fact that I'm using unbranded batteries from eBay (https://www.ebay.com.au/itm/256250808223). They've been charging fine, and the reported charge hasn't dropped much with each ride. Regardless, I now have a branded set on order. I'll also keep this bike for shorter trips for the time being, and be ready to pull out the seatpost should the problem reappear. May 26, 2024, 08:19:35 AM |

Re: LTWOO ER9 & ERX - Electronic groepsets
I upgraded from 11 to 12 speed today on my eR9 equipped bike. By:
That's it! This is such an underrated feature of this groupset (and the Wheeltop one too). Why go to 12 speed? I wanted to try the lightweight Goldix monoblock steel cassettes, as recommended by jonathanf2 on this forum. Those cassettes are available in both 11 and 12 speed, and I figured 12 > 11  I can also confirm that 11-34T, with 50/34T at the front, is at the absolute limit of what the derailleur cage can handle, so max capacity of 39. And the chain length has to be spot on at that setup. One link more, and there's too much slack in small/small. One link less (which is what I did at first), and the chain runs nearly straight when passing through the jockey wheels. And my B tension screw has only a few millimeters of additional travel left.

Re: LTWOO ER9 & ERX - Electronic groepsets
just came bike from putting my bike on the turbo because of the shitty weather here. I'm on app ver. 2.6.1 and all cassette speed options are available. FYI - If your smartphone isn't connected to the internet, the app can still access the groupset using the passcode (default 0-0-0). Someone asked what would happen if LTwoo went out of business and there are no updates or changes. At least if you have an older device with the app the groupset will be adjustable in the long term.

Re: Magene P505 PES Base Spider Powermeter
I figured a second charger to keep in my gear bag would be a good thing to have, I try to keep spares of everything I need often just in case. Given that it is proprietary, I figured proactively obtaining one would be a good idea. I emailed Magene, a month later they replied back telling me that it is $7, $20 to ship, and I also need to pay customs. Is there not an easier way to get one? Just look on Ali for another cable. It's the same as a lot of other PM's use. The Sigeyi Axo cable is the same for instance. Should be about 5-7 USD total July 11, 2024, 01:48:48 AM |
