What bike supplies do you carry?
What do you carry with you when you ride, and where do you carry it? I've got two main reasons to bike: commuting to school on the MTB and racing around on my roadie. I've seen posts from people who carry everything from CO2 cartridges to spare inner tubes for flats, portable repair kits, etc. For roadbike training I've been carrying nothing but a cell phone, a credit card, and a twenty-dollar bill.
