Butted Tubes
Bianchi One
product of Columbus
(custom-drawn tubes - bianchi named them.)
(it's pretty easy to get custom-drawn tubes
from reynolds or columbus, if you're willing to
buy 100+ pieces.)
The partial grouppo is Campagnolo Victory. The way you can tell is by
taper on the right crank spider. Lower-end Triomphe spider tapers in
a bowtie shape. Victory spider is a pure Trapezoid taper. The bad
news is that you will have the weirdo reverse threads on the left
crank arm or on both crank arms. Luckily, you seem to have
self-extracting bolts. I wouldn't remove & reinstall these bolts too
often, if they get stripped. you're totally screwed ...
The bicycle in my office right now (1985 Trek #510) is campy triomphe
(the lower model grouppo).
These grouppos were supposed to replace Nuovo Record (Triomphe) and
Super Record (Victory). It didn't stick. These two grouppos - which
were almost identical - almost killed campy - they were so plain and
downright ugly - in the early 1980's. The work great, however. Also,
the cranks are not anodized, which was a first for campagnolo, so they
can be polished to a beautiful shine without damaging the finish.
You appear to have the campagnolo retrofriction levers. These are an
upgrade from Victory/Triomphe (does it make them C-Record or Croce
D'aune ? I don't know.)
Someone has put a Shimano 105 arabesque derailleur on the back of this
bicycle, and they also did something to the front brake bolt and brake
pads.
The first thing i'd do is to put a chromed dome nut on that front
brake, it looks horrible with the nut that's on there right now.
