I wanted to swap out the 53/39 on my Colnago Master XL to a compact 50/34. It currently has a Dura Ace in it with Italian threads. Using a Park bottom bracket tool I took about three shots at getting the cups out and was not successful. Given the Colnago has such a great paint job, but one that chips easily, I took it off to my LBS. Well, they can't get it out either. It's now been three days soaking in an anti-seize agent and the drive side cup just doesn't want to move. I guess I wondering if additional time letting it soak will really make much of a difference. I appreciate their approach in wanting to be careful, but I starting to wonder if we'll ever get it out. Have any of you had experiences suggesting that more time and more anti-seize will really work? I'm looking for a ray of hope here.
