I'm contemplating another bent purchase, drawn to the simple efficiency and comfort of a high racer. I know I'm always hovering around 13-17 mph on my steel touring bikes, sure I'll pick up a bit on a high racer at some point. I've often heard and read that after 18 mph or so, most effort is burned overcoming aerodynamics. If this is true, what true benefits might the average bent rider gain from a slippery profile and high bottom bracket, if we're mostly staying under 18 mph? I'd love to hear some real world experience about this.

I might buy the bike anyways for it's comfort, and that I'm drawn to it, but should the aero factor even be considered? I know the answer is yes bombing a hill, or stuck in headwinds, what about the other 80% of basic pedaling?

Thanks in advance.
