You'll want to check this. Hopefully, they put the discs on the new Launch to be like the rest of the industry.
I think the video for the Hemingway gravel edition or was it the Mariner says that the disc is 15 mm inwards, but I don't think it's mentioned on the launch EX but I would assume there is a possibility it has this also. I would want to swap over my 11 speed cassette so I'd have to build a new wheel anyway with a new hub since most likely their hubs can only fit 10 speed cassette. Then I'd have to swap the brakes too.
I'm wondering though that with a 15mm offset of the disc, if the left and right spokes are now symmetric.
