I been checking out the new Dura Ace crankset and see octalink stamped on it. I have the 7700 series crankset, what would be the difference between the two???

It's just the spline pattern that Shimano uses on their BB's & Cranksets.. they have 8 splines as opposed to being a tapered rectangle. There may or may not be a stiffness advantage.. mainly its marketing. If you want to use a shimano crank, you have to use their BB.. If you want to use their BB, you haveto use their crank or a crankset bu a manufacturer that they have liscenced the octalink spline to.
Octalink is just Shimanos name for their splined BBs. nmgogene
