LTWOO eGR

[lavistaa]

You can get the rear mech on its own no issues, electronic mech is about 250USD. They are the updated design as well.  So far, my experience getting parts has been excellent and I’m glad they’ve decided to make all the cables and everything available.

They responded to my email, at least. They said it was a pity that they don't sell directly to consumers right now (I think he was responding to my question about whether I could purchase just the damaged link on the derailleur) but he would check to see if there was some other way he could support me. Maybe just pushing the problem down the road until I forget about it? Maybe actually looking for a solution? I'll find out.

They're nicely telling you to buy a replacement RD and leave them alone!

If it makes you feel better, a replacement GRX Di2 or SRAM XLR RD cost much more. Also I wonder if any of the mechanical LTwoo RD cages can be used with the ER9/X and EGR? Someone would need to do mechanical surgery, get a good look at the EGR cage and match it with their mechanical RD counterparts.

Not 100% positive, but I think I've seen some people on here get 50t cassettes to work, is that correct? I see this cassette on AliExpress just dropped to $68, it's 12 speed, HG, 11-50t and is under 400g. It's exactly
what I'm looking for, and I'm really tempted to go ahead and get this if it will fit with the eGR.

I am running both a 10-50 and and 11-50 11s Garbaruk cassettes (two wheelsets) with no issue. Used the standard hardware on the standard hanger on a 2019 Cutthroat. Yes a bit of B screw for alignment but not all the way.  On THIS bike, it works so seamlessly I don't understand why they don't claim compatibility with 50t for the win. Perhaps slightly different hanger geometries cause issues. Your mileage (km-age) may differ

Does LTwoo eGR show up in bicycle computers (wahoo for example) like Wheeltop EDS TX ? To see battery level and shift number ?

Yes and no. I have used it on Garmin Edge 1030+ and 1040 and a Karoo 2.  On all the gear setting report seems correct (there is a small latency but that might be normal for all eshift systems). But battery status is an issue on the Garmins. Even when full they throw an alert that battery level is critical. So no useful information there. The Karoo reports a status of full but I don't know if it updates correctly (it is a spare unit I just connected to answer this question)

Is anyone has news about two shifters operation of egr ? Very disappointing of this one hand use only.

Agreed. I wrote to LTWOO right after I installed and was told that they were considering adding configuration options in a future update. Unfortunately, no updates yet. I just wrote to them again about the battery status bug with Garmin too and added a PS about this again.

It's a real shame that the system has 4 buttons but you can only use 2. I want to see a configuration option of at least 'SRAM mode' (left side one way, right side the other) but even better would be to allow setting each button as you wish. And bonus points if they'd let buttons invoke ANT+ control of a head unit like Shimano and SRAM do on some models.  If you'd like to add to the pile of requests (please do) write to sales@ltwoo.com

Crash update.

I finally found some time to clean stuff up, take everything apart, and dig into what may have been damaged. I initially didn't think I bent my derailleur hanger, but I was badly mistaken. My derailleur hanger is quite bent. Which, is a good thing, because I should be able to get another one of those pretty easily and cheaply (though they are currently out of stock at Poseidon).

Bad news, though, is that I do believe the first link of the eGR rear derailleur is also bent. And maybe possibly my frame a tiny bit. I'll bring my bike the LBS this week and see what they think about the frame. Here are the pics of the eGR showing the link, below. Also, my bottom most roller was really, really rough. It looks to be a roller bearing roller and had water and crud in it. I couldn't disassembly it, but I was able to squeeze perhaps the tiniest bit of grease in there and it started to free up a little. Anyone find any replacement rollers that are confirmed to fit?

Does anyone have one not currently on a bike and can please take some similar pictures? It would be nice to compare and see if the little 3-5deg angle in that link is meant to be there, or is the result of my crash.

Are you talking about the jockey wheels? You should be able to remove them by taking off the screws. After that I'd clean the jockey wheels thoroughly with alcohol. Also I believe LTwoo uses Fovno or similar jockey wheels. You can find them either on AliEx or even Amazon. I consider most of the Fovno equipment to be decent, besides jockey wheels they make chainrings and their own crankset.

Yes, the jockey wheels. I was able to remove the wheel from the frame, but the bearing inside of the wheel was a closed, cartridge bearing. The bearing was rough, not just the wheel in the frame. Despite being a closed cartridge, I held my grease dispenser right up against the seal and managed to squeeze a tiny bit through the gaps. I could even see some watery/yucky discharge ooze out the other side. After that, it rolled much more smoothly. I can't imagine it's going to hold up very well for long, though. This was only for one wheel, the other seemed to be perfectly fine.

The good news is that jockey wheels are generally pretty interchangeable. You should be able to find a replacement without going back to LTWOO (Half of my bikes have non-OEM jockey wheels anyway because they look cool :-) )

This or wheeltop gx?
