I'm actually going through this process right now, although money definitely is an issue in my case. It's still a semi-custom frame from Joshua Bryant (which is being painted as I type this) with a custom front rack for my Berthoud handlebar bag, as well as custom bolt-on low rider racks if I ever decide to do any longer trips. The bike is designed for front loads only, and it will usually only carry the handlebar bag. For components, I'm reusing parts from my Univega that are compatible, with new parts where they're necessary. Since this bike will be 650b instead of 700c, I had a wheelset built with Grand Bois rims, a Schmidt front hub, and a Suzue cassette rear hub (I'll be using an 8 speed cassette). Concering dyno hubs and lights, I've made the switch on my commuter and my Univega (and now this bike), and I can't imagine ever going back to battery lights unless I just had to for some reason. For a headlight I'll be reusing the Schmidt Edelux I have on my Univega, and for a tail light I plan to adapt modern LED guts to an old Soubitez fender mounted light. I'm reusing the TA cranks and Shimano 1st gen XTR rear derailleur from my Univega, as well as the old Dia Compe cantilever brakes and brake levers. I have some 8 speed Shimano 600 downtube shifters I plan to use, and hopefully my Suntour Cyclone front derailleur. I'll also be reusing my Brooks Team Pro saddle, Nitto stem, and Belleri handlebars. Tires are Compass Cycles 650b x 42mm, with 58mm Honjo fenders.

Now if money were no object? I would definitely change a few things. But from a functional standpoint this should suit my needs nearly perfectly. Hopefully I'll find out soon!
