That is the first time I have ever seen brifters with toeclips.
This thread reminds me of classic car restorers and collectors, who fall into three broad and over-generalized categories:
1) Keep everything as original as absolutely possible, even if this entails manually adjusting your spark advance as you drive and tolerating a dim-bulb 6-volt electrical system, possibly even one with positive ground, which could get interesting (in the worst sense of the word) during a jump start.
2) Maintain the look and feel of the old, while taking advantage of modern technology, including perhaps electronic ignition and disc brakes.
3) Keep the body and overall shape, but freely build a hot rod with a modern powertrain, brakes, and electricals.
