I used to work in a bike shop, have a lot of friends/family pretty in to cycling and commute on a bike myself so I absolutely geek out over pretty bikes. Which brings me to one of my favorite brands, Pegoretti, a small extremely high end Italian bike frame manufacturer. My favorite part of these frames are not how they ride but the stunning hand painted finishes. These finishes are nice enough that I would be scared to take the thing outside and wind up hanging it on the wall as decoration instead of ever riding it. And that's saying a bit because I beat the ever loving crap out of just about everything I own.
