I put a rear rack on my cannondale and don't know how I commuted without it. It was a pain in the neck to do, took about 3 hours and about 500 4 letter words(should have been 15 minutes and maybe 2 four letter words). BUT trust me, I use it every day and my back loves me and now I don't DRIVE to work every weekend to dump my work clothes and food. I commute it daily! Good luck!
