The frame of my Colnago is now (almost) identified = Mexico 1985(?)
- and the gruppo as well (thanks for all the scanned catalogs I found on the net). The gruppo is a mix of following Campagnolo parts from different gruppos from different years:
Shifters = Victory 1986
Brake calipers & levers = Triumphe 1986
Front Derailleur = Super Record 1985
Front Derailleur = Record 1987/1988
Head Set = Colnago 199?
I would like to get rid of the non-campy components of my bike - Shimano Crankset & bottom bracket(?). I quess they should be replaced with crankset and BB of the existing gruppos of my bike. But which one of them?
OK... If frame is ´85 you have a few options.
If I were you I would be considering that
1) a Mexico is a top-end frame.
2) Triomphe was a bottom-end group
You might want to do something completely different with this project - the standard build for this would be non-fluted record cranks, Record all the way through - but Victory/Triomphe were a lot closer to the high-end than the low end groupsets are today.
Biggest problem will be sourcing a decent bottom bracket. If I were you I would leave "as is" for now. I have a Victory chainset you could have for next to nothing as it's superfluous to requirement. But the BB will set you back an arm and a leg.
Pedals - try and find some original Look or Time.
