It's been a windy spring here. I get blown around a lot in crosswinds. (Not as bad as when I had deeper wheels last year--terrifying!) Anyway, I was wondering if there are technique tips anybody has for dealing with them. My current thing is just try to relax and not ride too close to the edge of anything I don't want to get pushed into. Is there anything else that can be done?
As you mention stay relaxed, but mainly in your upper body and in your hands. You have to let the bike float a little. A trick is to move more of your weight forward over the front-end of your bike, lower your body position and push a slightly higher gear in the back.
Crosswinds and gravel pose their own unique set of challenges, especially if the gravel is loose and soft. My main piece of advice is watch the crown of the road. Either ride ride down the middle of the road, or on the flat on the side of the road. I've had my wheels blown out from under me while I was riding down one side of the crown.
