Hi. I am changing to a new chainring (I believe in a bmx it is a sprocket, instead). Anyway, it was difficult from the drivetrain side so I worked from the opposite side, I was able to remove the "pinch" and the other bolt but, this other bolt that goes on the spindle of the bottom bracket "stripped" the threads. I don't want to buy a new bottom bracket; can you please tell me how to fix this kind of situation. I believe the way is to tap a new thread but, I would like you guys confirm this to me. Also, what size should be the threading tool. Note, I use the " because I am not sure those are the proper words or proper spelling.
P.S. what torque to tight and which tighten first, the pinch or the "other" bolt.
Thank you all so much, in advance.
