I ride a Gary Fisher Wingra hybrid for commuting. Depending on which of my 3 likely destinations I'm going to, my ride is between 4 and 6 miles each way mostly on bike paths or country roads so I encounter little traffic but several fair sized hills. The thing that currently bugs me is that I feel like my body is a giant sail when riding into anything over a slight breeze.
What can I do to get myself in a slightly more aerodynamic position other than buying a road bike or just leaning down with my elbows way bent? I'm currently investigating my options (read bargain shopping) for putting pursuit style bullhorns on with bar-end shifters and road brakes without breaking the bank, but I'm wondering if there is a simpler and less expensive option. Would a new stem with a little less height and a little more reach do much good?
I'm not looking to turn this into a race bike, I just hate getting totally bogged down by light wind.
