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 were weighed 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.

it's 2x11 with 50-34 and 11-32
really looking forward to the outcome of your video call

I have Fix my problem take voltage meter and check V of batteries 14500 should have from 2.2v?? To max 4.4 (something like that), mine have 5.2-5.5V, now long 5h ride with new batteries ( this new have 4.2v) and 0 problem, 0!

Speed carbon has such rims (Peter from speed carbon on the forum)
Yuanan as well (OEM for Elite, also on the forum)
Farsports for sure
Basically you want rims that are at least 31-32-33-34mm wide.

So what are they implying?  Workers are selling them out of the back door of the factory?  There aren't any fakes or copies ..

Awful look for WheelTop if they or a third party marketing company are refusing warranty or encouraging people to believe that there will be no warranty on products unless bought directly from them ... despite the fact they're clearly supplying other retailers.
