Offered : one NOS (new old stock ), Colnago black alloy 42cm / 420mm handlebar , for 31.8 stem clamp . Bar never mounted , does not have a box. I tried to picture it , but at the one bar end it's engraved " 420 mm" , and how I measured it that would be center of one end to center of the other end = 420mm or 42cm. More of a anatomical drop ( I believe) , see photos for how the handlebar bends. This bar may have been made by ITM , pretty sure it's circa 2011 -2013 year range . Perfect to compliment a Colnago build .... steel, carbon , vintage or newer bike. I'll package the bar wrapped in thick plastic , in a box.
