Very cool bike! Thanks for posting the component list. Truly a custom bike and selection of components. The 46/30 with 11/28 will give you an awesome range to ride with. It's also convenient that the 11spd Shimano cassette is now compatible with Campy 11spd. The same combo is in the works on my current project. Love the design of the frame - the tall head tube with sloping top tube has a pleasing aesthetic and matches the stem angle. All very nice!
