in the spring Colorado Cyclist catalog there is a new short and bib called the Heliarc. It seems like it is a new premium offering (199/219). As I am training for my first Century I want the get the most comfortable shorts - for a long ride. I have Castelli Y2P's in bib and short and like them the most of what I have tried. they are getting kinda used in the past 3 years.( I see they now have a Ypro3). I want a bib which will provide the most comfort.
