It's been stuck for about five years when it resisted the best efforts of The Bicycleworks to shift it. It's a Dura Ace crank on an Octalink spline. It has a self-extracting bolt which is rounded to the point of being unusable. Is there any other way of getting this off than resorting to an angle-grinder as TBW suggested? I don't care about destroying the crank or the bearing but I want to avoid damaging the frame in any way. </p>
