Just got these new bars on my mountain bike. Haven't gotten to hit the trails yet because it's cold and raining today, but just around the neighborhood and yard they feel a lot better. Most importantly, I have a lot more leverage to pull the front of the bike up. Gary Fishers have such long top tubes and I'm not the strongest guy ever, I have always had trouble getting the front wheel over obstacles.
I think I'm going to order one of these for my Trek fx7500 that gets 1000 miles a month. bye bye flat/riser bars!
