I bit the bullet and sold my commuter, it just wasn't the bike for me. I still would like to occasionally hybrid commute home the 28 miles on my Cannondale until the funds are available for a Bike Friday I can double for commuting. I have a backpack but it isn't comfortable, anyone bike commute and use a pack? My Cannondale is carbon so a rack is not an option that I know of plus on weekends it is my road bike so I don't want to put anything on it.

I only have to carry home jeans/pants, shirt, underwear/socks, shoes, wallet and Blackberry.
