will an ultegra crank fit on a dura-ace BB (both the newer octolink ones)? Was pretty sure it will, but saw a site that says D/A BB only compatible with DA crank--thanks. Seems like a good way to save 50grams if you don't mind extra adjustments on the bb
new ones yes, square taper no.Dave Hickey

The square tapered BB's used different lenghts.
