Road bikes are not really suitable for commuting because they lack fender and rack mounts and your tire choice is extremely limited. Consider a country bike instead:
Trek Crossrip
Specialized AWOL
Surly Straggler
Salsa Vaya
Raleigh Roper
Diamondback Haanjo Comp
Schwinn Super Sport CX
Fairdale Weekender Drop Disc
Also called the alternative road bike or all rounder. They will also accept fenders and take tires up to 35 C. You can add a rack for hauling stuff. And they all have disk brakes for reliable all-weather stopping power under load. They are ideal for both on and off road riding.
