Hi - thought I might have better luck asking this question here than I did in the road forum. I'm building a new bike for my wife, and was hoping to find a blue 650c tire . . . after looking everywhere I could think of for the past two hours, I'd just happy to find a good source with a range of 650Cs set apart from the 700s so I don't have to click each model to see what sizes are available! Any recommendations?
