that does look troublesome for a one piece BB install.
That's exactly what it looks like to me- my R3 shell is designed for two-piece BB. I really wonder how the one-piece BBs were installed that some of you have. As I mentioned, I did talk to one bike mechanic who had installed one, and it sounded similar to mine. He was terrified it might get hurt and took extra time to figure out a way to make it work.
Are others like mine? I don't know- but I believe current production is like mine. I emailed this question to Cervelo with the picture attached- I'm curious to find out. Gary at BBInfinite says Cervelos used to have open, void space in the frame BB area between bearing shoulders.
