LTWOO eGR

[Noob Rider Adventures]

Ok, I said I'd be back with some info once I got it built. It's preliminary as I only have one ride on it so far, but you can read it here

Hi Thanks for this info, it's very helpful! it's been a couple of months now, hows it all going? have you had any other issues?

The thread may be that old, but my experience is fresher than that     I've had it out for another ride now. So far so good. I think I'm hearing slight noise sometimes on some gears like it may not be aligned correctly. So I might to go micro adjust better or I might go back to zero and do it per instructions (I micro adjusted first like an idiot). But functionally it's good. It's hard to directly compare the 'feel' to my AXS bike because that one is a 2x with a road cassette so each click is a smaller, smoother change. On the giant 1x cassette, some steps are a bit rougher by their nature. But I think it's pretty comparable. And definitely more responsive and reliable shifts than the modified, cable-actuated Force 1 on there before. I have no hesitation clicking up or down one to 'feel' right where there was enough faffing before I often just didn't.

You're right I got confused about the thread and when you put it together. All good info anyway. I ordered the EGR today through Aliexpress, really excited to get it. I'm curious to know if you've done a garden hose test on the RD with your Die-Electric sealer.
I'll share my experiences once I've put it together

 , yeah no. Not going to INTENTIONALLY antagonize it :-). I'll leave that to the people who got free samples. (Hey LTWOO, I'm game to test, hint hint)

My right shifter (i.e. the only one I use) is starting to have a minor issue with the lower shift paddle "sticking" a little after each shift. It has yet to cause any issues with shifting, but I can feel that it doesn't fully return to position after I press it for a shift. It's not a real issue (yet) but the OCD parts of my brain don't like it when my finger pulls back from the button and the paddle doesn't come with it and isn't in the exact same spot when I go to press for the next shift. I did a long ride in some mild rain the other day and, mid-ride, it quickly went from happening occasionally to happening after every shift.

I haven't really taken the time to carefully diagnose where the sticking is occurring and look for any remedies, but I'll take any thoughts from others that may have noticed the same thing.

on YT Trace Velo made a video where the issue he had with his paddle came from 1 of the 2 springs being misplaced. Have a look, it may be the same issue. Either on erx on egr.

I think I had seen that video a while back, but don't remember all the details. I'll have to rewatch it. I didn't think it was anything like that, though, because it was functioning normally for the first few hundred miles and has slowly progressed. I'll check out the video again. Thanks.

Modified my commuter gravel bike from Sensah SRX to Ltwoo eGR and so far quite happy after about 150km....
Gearing is currently 11Speed 42x 11-46 - I have a 12 speed cassette and chain ready to be installed.

Some have asked about water proofing, I went with electrical heat shrink tubing on the RD. I used an approx. 8mm shrink tube so it slides about 2mm on the connector port of the RD:



And this is how it looks connected with the heat shrink tube in place:



In case you wonder, could not get the cable through the chain stay since the connector is too long and stiff. Tried from both sides and finally gave up.
The routing tool with 5mm diameter passes in both directions but the stiff cable connector with the same diameter gets stuck and will not move..... I guess you can't always win

What firmware is everyone's unit currently on?

Mine is currently at v1.0.1 and has been ever since I received it. Has anyone received any firmware updates?

I had the same issue with my ER9 installation. I couldn't get the battery cable through the chain stay. I ended up having to route the RD cable externally. On top of that, my frame used cable tension for the shift cable access port underneath the BB. So I had to hot glue the cover to the frame and use a zip tie to hold it in place if the glue fails.

Same here. I'm hoping that is a sign of stability not...

Yes, same here. Frankly, I've got no issues that I think need to be addressed via firmware. It would be nice if they found something neat to do with those extra 2 buttons on the left brifter (maybe some novel shifting modes, or maybe a way to do data screen stuff on a gps unit, etc).

Yeah, I want them to let use use the left side buttons. Ideally assign at will.  But I see no reason not to simply allow both sides to be live. Personally, I'd like to be able to set them 'SRAM style' (up on one side, down on the other). I got feedback from LTWOO suggesting that they might do something. But no commitment.

Also going to write them about this topic! As more people might request this feature, chances will maybe increase that they implement it.

Hi @ChrisB,

many thanks for the idea with the heat shrink tube. Might work!

About the cable connector and about its stiffness and how long it is. Where did it got stuck? Near the RD in my frame I have this black piece where the RD-cable has to fit through. 2.8mm diameter on one and 6mm on the other side. I could possibly widen the 2.8mm hole to e.g. 5mm. How much is the diameter of the cable on the thickest part?

Kind regards, Dennis
