Windy days...

Those deep rim carbon wheels sitting on my bike are great.  Great for flats, great for rollers, great for non-windy days and even pretty darn good for climbing.  Here's where they're not good, when you're going down a descent on a windy day and cars/trucks are still zooming past you.  It's the first time I've really felt that instability and I think if I was a speed crazy cyclist looking to blast past 50 mph I'd be a little nervous.  Me, on the other hand, well I just focused on staying low and maybe feathering my breaks like a scaredy-cat every once in a while...
