It's been a while since I've worked on a Crankset with external BB.
I'm dealing with a Shimano Ultegra with external BB. My question is to remove the crank arms it is held together by two small allen bolts on the crank arm and one larger bolt in the crank arm? In other words it's not like a square taper crankset, right?

Also with the BB... the left cup is standard thread and the right cup is reverse thread? Just oppisite of the pedal threading, right?

Thanks, I'm trying to help some one over the phone with doing a bike rebuild.
