I have ridden them (the jeff jones h bar actually) I really like the hand positions on them. T
they are too wide for my purposes though. With the tight singletrack around me you really can't afford to go with a bar wider that 24''. Most of these types are a minimum of 26''. those two inches make a world of difference. And you really can't cut the ends down becuase you are eliminating what the bars purpose was for in the first place.
