I love my Motobecane Sprint. It's a great bike as far as I am concerned(though my experience with it has been like going from a used Jeep of an old MTB to a new Lotus). The thing is though, I really love the ride of old steel frames. Because of this I was thinking about finding a Masi Gran Criterium frameset, and using the Ultegra 6600 components from my Motobecane on it. They're not the absolute top of the Ultegra line any more, but they work very well and I already own them.
The thing is the Motobecane is wonderfully stiff, and I don't know how much performance I'll be giving up just to have the feel of steel and a vintage looking frame under me. I also don't know if this modern Masi steel frame will perform like a classic steel bike(it is lugged and uses Reynolds 525). It is designed around 700c wheels, and has geometry that is within a few tenths of a degree of my Motobecane in every dimension(except the wheelbase, which is like 10mm longer on the Masi).
Does anyone here have experience making this sort of switch? I'm asking here because you all have vintage road bikes, and if there is any crosstalk with the retro-modern road bike crowd I think I can paint an accurate picture of what this switch would entail.
Isn't it pretty?
