It looks as though there might be some confusion here.
The bars you linked to are the rb010AA, here, which from the description is shaped differently from the rb002 and some sort of collaboration with Tokyo Fixed.
The actual rb001 is in fact the same as rb002 with a 25.4 clamp (but im just going by a previous thread I found in bikeforums comparing the two bars).
Judging from the pics those rb010AA look to have less upturn on the horns and more curve on the bends, which I like. Wish I had found these before ordering my rb002's.
