You might try the iBob list or one of the randonneur lists, where there is a wealth of experience in building this type of bike.
The TA cranks and rings are perfectly compatible with modern 10 speed. I have a 10-speed Shimano Dura Ace cassette on my bike and have had no problems. In terms of bottom brackets, they just take a standard JIS taper. The Phil Wood Ti-Mg JIS bottom brackets for a double weigh 146 g (for 116 mm, which is for older Cyclotourist models) and 154 g (for 123 mm, which fits newer models).
I’ve never broken a clamp on a Huret derailleur, and there are plenty on E-Bay. Suntour Superbe front derailleurs also work well and are pretty. It is possible that with the newest model of TA crank (available at Rene Herse Bicycles in the US), you might be able to use a modern derailleur with a profiled outer cage.
Not sure how much the Mafac centerpulls weigh. I use Mafac Competitions. Mounted on studs they are quite light, though. Competitive with modern very high end brakes; in fact, they may weigh a little less than Shimanos.
If you’re going to use the bike for its intended purpose (long distance riding), it’s my opinion that there’s no substitute for clipless. Platform pedals can get quite unpleasant after a few hundred miles, although of course all the old greats rode quill pedals, but there’s no point in suffering! In general, you’re going to want to go with a mountain bike/cyclocross pedal; I really like Eggbeaters and they are extremely light.
Finally, some advice on working with a builder. It’s best to discuss the general intent of the bike with the builder, need for racks etc, give the builder a list of the components you want to use (including tires and lighting), have a quick discussion to ensure that you agree they are the best components for the purpose, and then set them free to do what they want. Don’t design lugs for them or try to select tubing or give them exact parameters for geometry. They are professionals, and even though we all know a lot about bikes, their expertise far exceeds ours.
some one knows a link to this "ibob" and "randonneur lists" sites?
