I have a stubborn bottom bracket that I can't get off. Are shimano B.B's reverse threads or not?

Bottom brackets turn in the same direction of backwards rotating wheels. aka the left cup is righty loosie and the right cup is lefty loosie. It's the opposite of pedals.

To clear this up, I believe this is incorrect. A standard mountain bike bottom bracket is a normal thread (clockwise tightens) on the non drive side, and a reverse thread on the drive side.

Sorry, I thought that I posted a message before I went to bed last night... I was pretty tired.

Thanks for the 411 but I had gotten the bottom bracket off by then and was out on my ride. I was in a rush to get out of the heat and before it was too late for a good ride.

I figured it out pretty quickly after I took the B.B. that wasn't cranked on so tight off of another bike. I had forgotten that old trick of following the wheels movement.

I don't know what kind of B.B. StringCheese has.

Oh whoops I said it all backwards! Yea forwards loosens. I'm glad you didn't go with my advice!
