I liked them on my Jamis, and am still trying to get them in the right place on this one. Seems like when they are right on the top, they're too far in the drops, but I think it's more the size of my shifters. I tried the Specialized Dolce bars first and sent those back as these were a better fit (and reach) for me. The measurement of them is a little deceiving. They are measured c-c at the drop ends but the drop ends are about 2cm wider than the ends of the top of the bar, (they flare out) and I wanted my top bar a little wider, so I went up a size and I am really happy with it. Not sure how they would be for racing or speed, as I wanted to be more upright, touring, looking around, waving (small town it's required) and looking for wildflowers to take pics of for Margo49 in Israel, but also having a comfortable bike for long, long rides.
I know there are others with these bars on this board. I've only been riding with drop bars for a year, so I'm certainly not an expert! I did do some research online and did find that the Biomax bars are for a more comfortable position and smaller hands. I found my options pretty limited, though, because I wanted silver.
