LTWOO ER9 & ERX - Electronic groepsets

I am so sorry if this is a newb question but what size bottom bracket is compatible with eRX 2025 groupset? Thanks.

The eRX groupset doesn't include a crankset. You need the bottom bracket that matches your frame (BSA, T47, etc.) and your crankset spindle diameter (24/29/30mm).

Oh okay this makes more and more sense! Thank you. What crank set and bottom bracket do you guys use and recommend?

Looking to get the TT-X68 frame which has a BSA Bottom Bracket.

Up to you what you want to use. If you don't plan on using a power meter, an Ultegra R8100 crankset is a safe bet. If you want a power meter, you'll have to do some research since there are so many options and price points.

Hi everyone, from what I gathered the er9 latest version has USB-C charging on the FD (not RD, that was a typo) like the erX. What about the buttons on the shifters? Did they update them on the er9 as well? I'm talking about the fact that the external button shouldn't encircle the internal one anymore but it should sit lower with a sort of step on the top. Does anyone have a picture of them?

On the erx the usb-c port is on FD. I haven't seen anywhere er9 new version. Where did you collect that info?

I corrected it, knew it was in front but wrote R by mistake! Question stands

Not quite sure what you mean by external and internal button, but here's a photo of the new "v3" eR9 shifter from a set that I just got. Apologies for the cling film.

This answers exactly my question, ty. I meant that the shifting button closer to the lever is taller than the other one, while in the first version they were level at the top.
