You forgot about the white saddles and white shoes. If you recall, we first saw an abundance of these (along with white bar tape) at the tour last year.

I've been using white bar tape since I got my ti bike in 2003. My newer road bike is white (and pink and silver), so white works great. I keep it clean with a little simple green -- it never looks too grungy.

I also wear white shoes.

And, I had a white saddle for a while -- just didn't like it as much as my favorite black one.

I would never, however, wear white shorts!

My motto is "if you can't be fast, you can be flash!" White is totally flash (and you don't need a mechanic to keep it looking fresh).
