Could you share photos of the relevant area of the RD and a link with the things you've applied?

It's nothing fancy. I just used Elmer's rubber cement glue with a brush that I coated around the battery cable. Plus a $2 USD packet of dielectric grease from the auto store that I applied with a toothpick. It just looks like gunk around the cable, I'm not sure there's anything worth looking at.

I only applied the rubber cement on the outside, but it dries and solidifies around the plug. After that I apply the dielectric grease as a secondary layer. I didn't like the idea of just using dielectric grease by itself since it's easy to take off. I figure the rubber cement should ward off most moisture, while the dielectric grease would be like frosting on a cake.

I got the idea because I had a leaky water sprinkler at my house and I sealed it with rubber cement. It actually did a very good job fixing the problem.

people have had success using liquid electrical tape around the RD cable plug. i bought a bottle myself but i don't have a thingy precise enough to squeeze out the stuff with any precision, so i'm not sure how to seal it efficiently. the stuff is sticky and dries super fast so it's not forgiving at all.

I used liberal amounts of rubber cement on the battery cables. It's a non-permanent adhesive seal that's easy to rub off. I then put dielectric grease on as a second protective layer. I haven't rode the bike in the rain, but it's been adequate against random water puddles and other wet areas. The only issue is that the dielectric grease attracts a bunch dust/debris. I'm thinking, maybe using rubber cement and then applying heat shrink plastic might be a cleaner solution.

This is pretty dumb. How hard is it to assign a serial # to each groupset? Their warranty process is just pure laziness. The EDS TX is already in Shimano 105 Di2 AliEx pricing territory. At least with the 105 Di2, spare parts are plentiful and quality assurance to chance buying from a reseller is much better.

where are you located?

Southern California. When it does get wet here, I usually just take my mechanical GRX gravel bike.

Any chance SPcycle will do a lightweight climbing frame with T47 bottom bracket and 32c tire clearance? I know there's the SP-053D, but I'd prefer not to go with a BB86 frameset. I have an older SP-027D which I'm quite happy with. Though I might be interested in getting a climbing frame in the near future.

Lol those holes are the most retarded pattern imaginable, it's almost funny. imagine the donkey who came up with the design.

They work fine! I double checked my gravel bike brake pads which does long descents on dirt trails and there are no deep track lines on the pads. My 2x160mm rotors are 1.6mm thick and feel quite sturdy. For someone to toast their rotors and dig tracks into their brake pads suggest to me they weighed like 130kg and had zero clue how to feather and modulate front/rear braking! There's a reason they have bigger rotors for bigger riders!

My ER9 is still going strong. When it works, it's f**king great! Though I'm not ignoring the problems. Hence why I don't ride my ER9 bike in the rain & don't wash it with a hose, I rotate my bikes to minimize wear-n-tear and I don't do things like shifting both the left/right shifters at the same time.

Also I'm theorizing that some aftermarket batteries might be an issue as well. That's the one variable that differs between all the working/non-working units. This is probably why Shimano uses their own proprietary unit and SRAM insist on only using their OEM batteries. I could imagine a sh**ty battery could potentially toast the ER9/X RD electronics.

Even with all the issues and the non-existent LTwoo support, I'd probably buy another ER9 groupset when it's on sale. The performance-price-risk factor is still worth it for me.

And the disaster continues. 3rd dead er9 RD. again, randomly and for no reason. Was riding with my friend, who really hasn't used his new bike much, less than ten rides for sure. Dry, 20 Celsius, smooth asphalt, largely flat. 35km into the ride, his RD dies like the other 2. So there's my er9 on which I've put almost 4k km that's working fine (sometimes it charges weird, but at least it's working), and the fifth one isn't being used because the front wheel on that bike broke during a crash and we're still waiting for a replacement.
At which point can I preemptively ask for extra spare RDs? I'm happy to beta test, but we can't be 6 weeks without derailleurs every time one kills itself.

It probably wasn’t a good idea to buy 5 ER9 groupset especially since it seems LTwoo hasn’t ironed out their issues. My ER9 is still working fine, but I’m always checking to see if it’s functioning! I’m already eyeballing some cheap mechanical 105 12 speed shifters or just drop back down to 11 speed with spare Ultegra shifters if my groupset does die!

BTW - LTwoo updated the app, but I don’t see any new features. It looks like they updated it to recognize the upcoming blue edition ERX/9.

I have to say that I strongly discourage the use of this disc rotor. It completely neglects mechanical simulation and the bracket itself is prone to fracture. Furthermore, the pattern design is a mess, with hollow patterns distributed unevenly on several concentric circles. As a result, the friction rate of the entire disc rotor in the radial direction cannot achieve consistency, leading to the formation of grooves on your brake pads... It's a design that leaves me speechless.

The issues mentioned above are not exaggerated claims but rather highly probable events that have occurred multiple times on Chinese forums. I don't want anyone else to become a victim of this disc rotor.

I'll just flip the pads around to even them out. I rotate my bikes every other ride, so I'm not too worried!

I had a problem getting the ER9 LTwoo calipers+140mm adapter plate to line-up properly using 140mm rotors on the rear. I tried it on 2 different framesets and both of them would not line-up properly. The strange part is that I had no issues running 160mm rotors with the Ltwoo calipers+adapter plate. I ended up switching over to ZRace XG calipers which required no adapter plate. I literally just unscrewed the Ltwoo calipers and screwed in the Zrace calipers, plug-n-play style. They work well enough with no issues on long descents.

Seen it last week and it looks like the cervelo/focus one, but it's not even cheaper. Got one at the LBS for 25CHF, seen it even cheaper on bike24

What are the 150/102/135mm sizes?

For people who want to spin at 400 RPMs!  ;D

Yeah, I think the seller should clarify that part.

Anyone see this new carbon crankset? It has 165mm, 170mm and 172.5mm crank arm lengths. The Riro and Racework cranksets are only 170mm.
