Here in the Sacramento area, it's been much windier than normal. My wife always had a lot of trouble dealing with it. She's pretty small, at about 105 lbs. We really worked on her technique this year, and she's doing much better. Here's what we worked on....
- Proper posture. Use your core. Don't lean on your hands. Roll your hips forward, flat back, support your weight with your core. For this to work, your saddle has to be in the right position so that you are well balanced over the cranks.
- Relaxed shoulders, arms, neck, etc. and relaxed grip on the bars. Staying loose and relaxed allows your bike to self-correct when a gust hits. You will no longer be fighting the wind, but instead being "with" it.
- The wind is there. This is the attitude key. A nice calm Zen attitude helps quite a bit.
