In that era first quality SP ( 27.0) and SL (27.2) frames
weighed less than the 'tretubi" economy models (three tubes
Columbus with heavier cheaper forks and stays) yet have the
same post sizes.

Since the seatpost diameter is 26.4 what would you expect the tubing to
be? I have an early 70's Stella with tretubi Columbus main triangle.
Seatpost diameter is 26.4 or 26.6 (I don't recall which, the bike is on
loan to a friend and I don't have access to it). Antti said the frame
alone weighs 2.4 Kg.

The rear-changer looks like a 980, not Nuovo GS. If the frame is unmarked
the tubeset could be from Falck or Oria. The front-changer with the flat
(stamped) outer arm is in a supplement catalog as "Nuovo Valentino". There
are two Gran Sport front-changers in catalog no.17, a renamed NR (1052/1)
and the old box-type (2050).

Hey Antti and Bill, et al, Try this!
http://www.yellowjersey.org/salonen.html


ps: this link

http://www.yellowjersey.org/ebay/mcr.html

works for me. Dunno.

And I believe the Stella to which you refer was both Metric
tube ( 27.2 becomes 26.8 in the same gauge) and either a
butted seat tube or a straight gauge tube set. They were
nicely built, straight, very well priced at the end but not
excessively light.

Thanks a lot. The Gran Sport model at the bottom looks pretty much like
the same bike, although with a different paintjob. I got one of those
D'Alessandro tubulars with the bike (under the saddle as a spare) and
the 3T seatpost seems to be exactly the same. I guess this would date
the bike to the late 70's, but with some parts like the saddle having
been replaced later.

Andrew, it must be a hoot looking through your basesment. I had
no idea Guerciotti had so many models. -- Jay Beattie.
