Does anyone know how much your seat bag affects the aerodynamics of the bike? I've been racing with the same bag I use for road riding, a Topeak medium aerowedge. I see lots of small bags now called speed bags. How much difference could they make? I would think my legs would be taking the brunt of the wind in that direction, but I'm no expert. Thoughts?
