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.
