Yes I am aware that the DS cup is left hand threaded. These cups wont budge at all. When I went to my LBS they told I can take off the cups with just an adjustable wrench and some channel locks but I have not been successful. Thanks for the tip though I was pulling my hair out trying to figure out if there was another angle to this. I watched a few youtube videos but I guess I havent found one with a good explanation of what tools are needed.
