In lieu of ordering a custom lugged frame, I came across a beautiful 1969 Schwinn Paramount frame. I would like to install modern componentry instead of older classic Campagnolo components that it originally shipped with.

The Paramount is frame-only, with no headset, crankset, bottom bracket, seatpost, handlebars, brakes, or wheels. My goal is to install a modern wide-range indexed derailleurs, modern sealed headset and bottom bracket, modern dual-pivot brakes, etc. I had the rear triangle respaced to 130mm from the original 120mm spacing by an experienced frame builder, so it is aligned properly. He said 120mm to 130mm spread is as far as he would recomment.

Here is what I was thinking:
Chris King threaded headset
High quality sealed bottom bracket (Phil Woods, or is there something as good but cheaper?
Sealed hubs, with 9 to 11 cog rear cassette
New crankset (should this be a triple or a compact double?)
New polished rims
Brooks B-17 or Professional saddle (I have one of each already)
Randonneur handlebars, with bar end shifters (I don't like brifters)
Dual-pivot brakes with enough reach and clearance for 700Cx28 or 700Cx32 tires.
I may install nice polished stainless fenders as well, depending on spacing.

I'm basically a C&V retrogrouch, and my other Paramount has full Nuovo Record Campy componentry.

The gearing is the question--I want a wide range setup, with very low gearing so I can ride up mountain roads.
I know many use compact double cranks with wide range (11-32) 10 or 11 rear cogs. But does this work as well as a 24-36-46 triple?

Thoughts and recommendations?
