i've never ridden the dirt drops. but roll with the specialized BB1 on my foul weather fixie, and they are a ton of fun. they feel a touch wide to me, but i normally roll on 36's, so nearly everything feels wide - oh yeah, and they are silver (Al) as well
the picture doesn't really give you much info on the bars, let me know if you'd like a better/more pics of the BB1's
