So, I rode the Jeff Jones H-bar on 4-5 rides. I wanted to love it, but it just didn't feel right. I put a longer stem on per everyone's recommendation (I normally run a 90mm Stem and put on a 110mm). First ride with the "los" at Madrone, I liked the sweep, but nothing else. 1/3 of the way through the ride, and my hands were numb. Second and third rides showed the same results, and on my final ride with Alan @ Flat Rock Ranch, I was through with them. Hands numb, and I felt that the extensions were useless. I also never rode in the position everyone said was their favorite at the junction of the extensions and the flap portion of the bar. I didn't play around with angle, or even try a different length. After much frustration and a considerable investment in a bar, I'm done.
I decided to put my 90mm stem back on and attached my EC90, rode it last night and felt very comfortable. No hand numbness, although I did miss the sweep of the Jones bar. My next move will be to slap on the Mary bars and see how I like them. I may just be a riser bar kind of guy.
