I will say custom........but that is shaded by already having a de rosa
At this stage in my life I want a custom at some point..... and a true custom is not just about if a person is an odd bpdu size. It is about getting the all little details and over all tuning, even custom fork
Personally I really want 2 Dave Kirk customs (call them my grail, bucket list what ever) this is what would do now for the build (subject to change as time goes by
1) What he call a Montana Road bike. Clearance for big 28 to 30 or so with fenders, fender and rack brazeons, Nitto cockpit and seatpost, brooks saddle of some sort, probably ultegra hydraulic disk, possible non parallel to ground top tube to allow little more put a leg over room in the future. vision is a fast all weather commuter do every thing bike. My zombie Apocalypse bke.
2) Light, fast road bike. Only used on nice sunny days. level top tube, chain hanger and water bottlle braze ons, Nitto cockpit and seatpost, Tubular wheels, light seat (brooks or sella italia) Dura Ace. (probable electronic shifting, especially if Shimano ever goes wireless....... or campy if campy beats shimano to wireless (don't like sram)
