Rebuilding my Perthus Pro

[BigFoz]

So the Perthus i bought back from my wife's uncle (whom I sold it to in 1993/4) needs to be built. I'm going to go with a "light" build without any carbon, just to se what a 30 year old bike can build to - components i have already have been weighed, the rest looked up in catalogs etc, and it appears I can build the bike under 18lbs without actually going out and looking for mega light bits, and using the components i already have put aside.

So the first question: Colour...
Do I go "original metallic Graphite", or like my rebuilt Superissimo, go with something different? Was thinking a Gulf Mirage/GT40 homage... (I was very taken by this Laverda SF I couldn't afford

It might be tempting to change colour but that Graphite looks really great.
I would buy one myself if I could find a good 58cm one.
What are you planning to fit it with?

Re:

same as my first race bike,which was in graphite.it I remember mine had a strange seatpost with a expander inside the seattube and no bolt

Components will be mainly a mix of period correct Record / Chorus, finishing kit might vary as things like aero Record seat posts are ludicrous prices. It's a long time since I last worked on this bike, anyone know whether the seat post is NOT 27.2?

Looking through things like Weight Weenies lists and catalogs, and weighing the bits I have, I've been surprised that 30 year old components aren't hugely heavier than current models. In fact some bits are lighter than modern components. Example, down tube + aero brake levers are lighter than Ergos, and also use less cable outer, making more saving.

I've got my 653 framed ribble to 8.95kg with a centaur/Daytona 10 speed ergo groupset, and no weenie parts at all.

it wouldn't be that hard to go lighter either

Yes, my 531 Raleigh runs in at about 9.5kg in current trim with it's 501 fork. You can lose a lot of weight just by choosing light tyres. If you don't mind the increased puncture risk, I shaved off 300g by swapping from the old steel banded Hutchison Kevlar 700x25c tyres to Michelin Pro 3 700x23c. Other obvious things are non-aero rims (which are slimmer and tend to be lighter) , 32 spokes instead of 36, cut the excess seatpost length off, slim alloy pedals and use a light saddle like a Flite Titanium. There's also quite a big range of weights for handlebars and it's worth comparing.
