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?
According to Specialized's bike archive, that's a "Specialized, oversized integrated" bottom bracket. I *think* they're based on BB30, so you'd use BB30 adapter thingies like these, to get your Hollowtech II crankset installed: http://www.pricepoint.com/detail/206...p=030%20WHEB30
That's awesome guys. Quick question though, her old frame is a nice 68mm, however her new frame, the '08 Specialized Ruby Pro is only about 64mm. I'm pretty sure the standards are 68mm and 73mm. Can we still use the 68mm adapter on the frame given the 4mm deficit? Should I put spacers on that or just having 2mm on each side should be fine.
Do these adapters have any problems with sliding left and right after being pressed into the BB30's?
