I consider myself a fairly competant home bicycle mechanic, but for the life of me cant figure out how to get this Quick Link Apart. I watched some vids online of people just pressing them together and voila. Is there a trick with the newer black 10 speed quick links? I have had 10 speed on my last bike and it wasnt that big of an issue. Also can you put a 9 speed quick link in its place without any issues? Cheers Chris.
