Cannondale, at some point, switched from a 104mm spindle to a 109mm spindle to accommodate the BB30A system. If you put one of those BB30A spindles on a BB30 frame, you will need a spacer to fill the gap between the NDS crank arm and the frame.

Also, Sram requires spacers and pre-load adjusters on some BB30 cranks (those with carbon arms and removable spiders), which space the arm from the frame: https://www.sram.com/sites/default/f...brackets_0.pdf

The full carbon Sram BB30 cranks, like Sram Red, are flush with the frames.

This is our second time around on this...lol.
For you to extrapolate your comments from what I wrote suggests no amount of words will create agreement. Of course what you wrote is true but it isn't what I wrote. I wrote all BB30/PF30 'BB's' are flush...not cranks. Of course spindle lengths vary on 30mm dia spindle cranks which requires different spacing...or not.
That is my last attempt.
I admit surprise we are talking past one another so profoundly because I generally agree with you on the forum. If you care to, re-read what I wrote that you quoted. I said 'bottom brackets flush' not cranks. Spacing of cranks may vary. As plain as day. Come on tfp.
