The factory Kona handlebar weights 607 grams. The Misfit FME bar weights 336 grams.
To install it, I had to pry the stem clamp open a bit to slide the centre section of the handlebar in. I probably could have rammed it in, but I didn't want to scratch the finish. =)
The FME's riding position feels similar to the bar it replaced, and has more handlebar/knee clearance for tight, slow speed turns.
UPDATE NOVEMBER 11, 2011: The price of the handlebar went up. Yikes!
UPDATE NOVEMBER 18, 2011: The extra bit of drop and reach from this bar puts extra weight over the front wheels. The bike feels more balanced and puts me in a slightly more aggressive riding position.
UPDATE NOVEMBER 28, 2010: I can feel the handlebar flex a little on rough surfaces. It takes a little edge off the bumps.
