Cannondale CAAD8 105

My first proper road bike. Purchased after shamefully owning a Viking 'road bike.' After various run-ins with vandals I've upgraded the group from Sora to 105 and swapped out the stem and handlebars. Added some basic Shimano r500s when the rear hub on the original wheel sounded like a pepper mill grinding through cocopops. Just need a black saddle and I'll be more or less content. Considering some kind of respray after another winter or two.
