As I've mentioned before, I'm gonna use my Bianchi Bay City '07 hybrid commuter for some light touring. Touring aside, what about some semi-knobby tires for commuting? I'm gonna have some Mavic A 319 rims laced up. They accept 28-47 mm tires. I know I won't be able to ride fast, but then again, I'm commuting, not racing cars. I do have the option of buying them and switching between my commuting tires and the cyclocross. Please feel free to comment.
