Hi again, the bar looks like the one you'll find in this other thread:

The arced one, not the butterfly; compared with that steer. Mine is a different in that the smaller tube is bigger and attached to the front bar a bit more to the ends,
Actually, after work I went to another bike dealer who's into Specialized/Cannondale - He handed over some grips with "ergonomic plateaus" to be more comfortable for your hand - I can check them and if they don't work I can return them. They also have a small metal end grip, that may overcome to slip away with your hands, but in themselfs offer another extra grip. Hope my English makes sense...
