420mm. Amazing handlebar. Stiff and light.
180 grams on my Feedback scale. The stem clamp area is reinforced with titanium mesh. Notice in the 4th photo that there is a chip in the gloss coat. Didn't even notice it till I was taking pics. Doesn't affect anything with the bar. I assume this happened when removing bar tape. Also, in the 5th pic you'll see a scrape at the end. Also doesn't affect anything.
Compare this to any bar available and nothing can match it!
