Reposting this from the Road Cycling forum as it wasn't getting much there.
Hey guys, I have question about transferring parts from one frame to another. My gf picked up a used '08 Specialized Ruby Pro frame and we're moving her components over from her old Specialized Allez Comp frame. This is a learning process for both of us as this is our first bike build so we're open to all new info.
I'm looking at the bottom brackets of the two and I realized that a simple transfer isn't going to be enough, the old frame has a sealed BB and the new frame looks like the picture below. This is a press-fit bottom bracket shell right?

Is there any way to get this working with the old sealed bearing BB? I'm assuming no :(
If that's the case, she's going to need a new crank which brings me to my next question. Right now she's on Ultegra 6500 9-speed but in the next few months wants to upgrade to a 6700/7900 grouppe.
Can she upgrade her crank to the 6750 crankset right now and do the rest of the upgrades later? I mean a compact crank is a compact crank, it should be able to work with 9 or 10 speed cassettes right?
Finally, where the hell do I get the Hollowtech II press fit bottom bracket?
It seems the only press fit one they make is for Dura Ace (Ultegra doesnt have one), but I Can't find one anywhere.

SM-FC7800P Hollowtech II Bottom Bracket - Press-Fit
I've heard varying things about the FSA BB's, both good and bad. They seem to have one that works with Hollowtech II.
Thanks again guys.
