Crank Brothers Iodine 11 Carbon All Mountain Riser Handlebar
I took these on two very long rides this weekend and they performed beautifully. They measure a touch narrower than Easton's 680 riser bars but it's close. Not only do these bars lighten you for the uphill, they also were solid on a 15 mile descent and over several 4-5 foot drops. I found these bars to be one of the best gram-shedding-per-dollar investments as I was building up a new bike.
