Thanks for posting the link, but now that I have read the blog post, it still looks like you need a bottom bracket shell capable of accepting a 30mm spindle.
Edit: I later confirmed with them I wouldn't be able to use it. There is not enough room for my Di2 wire and their 30mm spindle. If I did not have the Di2 wire, I might be able to get it in there.
