Super lightweight but very rigid set of mountain bike handlebars that came off my newer bike when I moved to 29" bars. Specs for the bars say they are around 155 grams, and have a 40mm rise. These are the 31.8mm stem version.
They were clamped pretty tightly to the stem when I took them off the bike, so there's a mark on the bars I show in the second picture.
