At some point the wind can get strong enough to blow anyone around. The heavier you are the more it takes (all things being equal like tire pressure, rim and frameset, speed, etc.). I feel crosswinds more going downhill and once I had a front tire going down and a strong on-shore wind at Del Mar made it feel like my brakes were on. I guess I'd like to go as aero as possible without getting pitched across the road into traffic. There's some video of guys getting tossed like rag dolls in a crosswind. At least we can usually still ride. GL
