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

In order to run the cable housing all the way though you need to remove the bottom cover under the bottom bracket and make the holes slightly larger for the housing to fit through. Also need to Remove the metal fitting on the chain stay so the cable housing can come out, nothing else besides that. The metal fitting is removal, for those that run electronic you replace it with an included rubber grommet. It worked fine. I did end up going with an Egr groupset shortly after. No issue with the mechanical groupset. Just couldn’t pass up Egr @ $360

Hi Trackar

Thanks for sharing this. How do you find the EGR? I'm keen to know if the problems of the Waterproofing and the RD swing stop has been resolved? The one that Luke from Trace Velo was having.
