I am installing my evil chain guide right now. when I pulled out the bottom bracket, something really wierd happened. Please keep in mind that i have been a shop mechanic for 4 years, so I'm not a total idiot when it comes to installing BB's. Ok I backed off the non drive side cup about 5-6 full turns, then went to remove the liped drive side cup, and it came out. with out the bottom bracket. I am using an XT square taper, UN-72. I have lots of extra XT's (none the right length) laying around so I pulled some out, and sure enough, the drive side cup is fixed to the bottom bracket. Better yet, when i took out the non drive cup, the bottom bracket was stuck in it!?!? I can put it back together the way it is, but am I going to have problems with it coming loose or creaking??
