A stem with higher rise should help immensely--in fact that may solve your problem. It's surprising how much of a difference in feel can be caused by small changes to the bike. Also, have you tried rotating the bars up just a bit--this brings the hoods closer to your hands. And if you can, without compromising your leg position, moving the saddle forward a little bit might help.

You might also try smaller handlebars. My Bianchi Veloce--also new--has a bar called "Deda 4 Girls"--and it's the tiniest little devil I've ever seen. It's even smaller than the Salsa Poco bar I've got on my touring bike.

Hang onto that hope! The new stem may be just the ticket.
