I've currently got mountain bike-style riser bars on my commuter, and was thinking of switching to something like north road bars. However, it gets pretty windy around here, and I was worried that the more upright posture would slow me down to a crawl in windy conditions. On my riser bars I'm leaning slightly forward, and can get slightly more aerodynamic by holding the bar on the lower middle section. Is this possible/how do you deal with wind on north road bars? I suppose I can always sit on the rear rack...
