Anyone care to weigh in on this?
What they're probably thinking is that for sure with the old Gates system the pulleys had to be in exact alignment. You usually have to have a shim-able BB to get them to line up, which the FSAs are. Many others are not. I swapped out our Race Face BBs for FSA for that reason. I expect perfect alignment is best with the CDX also.
