+ 1 for the Ahearne/Map and trying your present stem. I'm a dedicated drop bar rider too, but know a little something about upright bars because I've tried so many and didn't like them, always going back to drops. But I have to say that the Ahearne Map bar is the best non-drop bar I've used, and once settled on my Monocog 29er with 9 cm + 17* stem, the same length I'd use for a drop bar, and with Ergon GP something grips, it's actually rather comfortable. I did buy the shorter one and cut 4" off each side, but that's another matter; the bend, the width between the curves, the very slight drop (I installed it with drop, not rise), and the road levers installed at the forward end of the curves (I can brake from the "hoods" all the way back to the bar ends) make it -- well, again, not bad at all. And once more, I tried many, many upright bars and disliked them.
As installed and gripping the Ergons I sit more upright than on the hoods of my other 3 drop bar bikes, but I can lean forward and grip the curves (double wrapped) and even wrap my fingers around the (horizontal) hoods. Not bad at all.
Still, might just try swapping in a 44 cm Specialized "Hover" bar with 15 mm rise to the flats and ramps. (Anyone have one for sale?)
4" trimmed from each end; of the bar 1" trimmed from forward ends of the Ergons, double tape between ends of Ergons and far side of levers. Bell is now more intelligently clamped just forward of the yellow tape. But point again is not cropped bar but the hand positions at ends, along curves, at hoods, on hoods; from comfortably upright to moderately aero.
