some dimensions here
rive_gauche-
Thanks for that, an interesting read.
Still confused about the their whole naming logic, Superleggera, Specialissima, Super Corsa, Reparto Corse, Campione del Mondo, Rekord, etc. Seems very 'fluid'.
Oddly, it says it's a 1980 catalogue, but then page 2 say 'Frame Dimensions 1982'.
And then adds yet another raft of model names: Sport, Touring, Special, Pro, etc...Weight-wise, I'm waiting now for Colnagodaft to tell me it's definitely a Raleigh Night Burner, 'cos it's got the same number of wheels as one he's got in his workshop...

Ok, first check...
Scales are working fine. 125g yoghurt weighs in at 131g on the scales, which seems about right allowing for the packaging.
Off to the basement again with the digital scales, giant spanner and a bottle of fine Belgian beer (La Chouffe)...
Fork off. Various bits of headset off too.
Second check...
Fork + several bits of headset = 816g
Frame with rest of headset (+bb) = 2112g
2112g + 816g = 2928g (stacks up against the 2925g original weigh-in)
So, without hammering the rest of the headset off the frame...
Headset weight is approx 200g.
Say half of that weight is on the scales with the fork?
2112g - 100g = 2012g.
BB weight approx 300g?
2012g - 300g = 1712g
I took off the seat bolt, but still on the frame are the rear dropout screws, and the bottle cage screws. I'm going to take that lot as 12g.
So that gives me a frame weight of 1.700 kg (give or take about 50g I reckon).
The frame is 52cm, so upscaling that to 54cm would surely not be more than 1.800 kg...?
