Absolutely not.

Time trial bikes are pretty fast and they don't have drop bars on them.

My bike doesn't put me any more or less in the wind than a rider using drop bars just because my handlebars are flat.

I don't have super low bars, but many road bikers sit up higher than me. It's depends on handlebar height and reach, not handlebar shape.


And I have lots of hand positions with these barends. Holding the ends of them and putting my elbows on the grips puts me in a very aerodynamic position.
