I commute 34 miles to school using my road bike.
I figure that I've spent so much money on my bike why not use it as much as I can?
I'm 100% dialed in on my bike so comfort isn't an issue.
All I need to bring is packed in a nice Deuter backpack.
Lastly, I don't have another bike and I don't want to spend money to buy a bike just for commuting so that makes the decision alot easier
