As 79p said, they are a real bear. If you're in a criterium they are OK because you can go before you change or after, but for a long ride with indeterminate toilet stops they are a pain. They have a few advantages, they keep your shorts from sticking onto the end of your saddle when you have to stand and sit a great deal. And they are cheap but have good pads in them from the Chinese. Since I ride a lot on the street I want really bright clothing so that I am easily noticed. Except for a few years most team kit was made to be noticed so that's what I buy. Though my winter kit is a great deal less selective leaning more to the warm than to the Look At Me.
