If your road bike has an exaggerated racing position (butt way up, handlebars low) then you *might* need a different saddle than a Brooks on it. Riding with hands substancially lower than your seat can put more pressure on the girly parts up front. I don't know how your road bike is that way, do you have any other saddles you have liked in the past besides your Brooks? Can you try them on your new bike?

Lots of people do their daily commute on hybrids, city/touring, or mtn bikes because the racing position is not the most comfortable for basic transportation, especially in traffic. Just a thought.
