Hello,
I recently bought a bike with a Pogliaghi frame, which is in quite a sorry state. Unfortunately the decals don't shed much light on what steel was used for building the frame. Any help would be much appreciated for identofying this frame as a model, if it really is a Pogliaghi and not a cheap knockoff and what tubes it is built of!
Thank!

Strip it, weight it, and find out what diameter seatpost fits.

Is there rifling in the steertube?

Nice bike whatever it is. Are the markings on the fork crown cast into the crown? I'm no expert on Pogs but I would think those markings may be helpful in figuring out what you have.

by the graphics it's "real" but from the era that these were made by Rossin (probably) or Basso: Sante was gone and sold the name.
This MIGHT have been sold by Performance, if retailed in the USA.
The size of seatpost will be a good clue as to tubing, but given total lack of chrome and the "Columbus" DOs, I'd be inclined to guess "Aelle"

That brake bridge adrift on one side?

Based on the stay to dropout transitioning, it's not a frame built by Sante Pogliaghi. The BB cup has a February 1988 date. Assuming it is OEM, that's close enough to the 1989 brand transition from Rossin to Basso that it could go either way.

Had a very busy week, sorry for the late reply. The frame doesn't have rifled tubes - so SLX is out of the question. The frame alone, without BB or headset cups weighs 2020 grams (it also measures ST 55 cm c-c 56 cm c-t, TT 56.5 cm c-c, DT 63 cm c-c, HT 13 cm). Regarding the seatpost diameter, I still haven't got to measure it, I borrowed my calipers to a friend and didn't get it back yet.
Also, here is a picture of the underside of the BB.

That serial number may help withn the identification. If we assume a Basso product, then the serial number represents 1991. By then, all of the top three Campagnolo groups, Record, Croce d Aune and Chorus had all gone to 8 speed cassette hubs with 130mm dropout spacing, along with Shimano's Dura-Ace, so I would expect a Columbus SL or better frame to have 130mm spacing. Consequently, if we can verify the tubest and rear spacing, that may aid in the identification and help determine the orignality of the Shimano bottom bracket. Has the inside bottom of the fork's steering tube been checked for the five helical ridges indicative of a Columbus steerer tube? Also, what grade is the Shimano bottom bracket spindle?

dbalu 

I have just checked, the steerer tube indeed has helical engravings looking from the fork crown. The BB is a standard 6400 series Shimano 600 BB with Italian cups and 70 mm BB shell spindle. I have asssembled it back so exact spindle lenght will be provided when I get my hands on some calipers to measure the rear spacing and the inner diameter of the ST too.

Can you feel or see them in the bottom of the seat tube or down tube?

T-Mar

You don't need calipers to measure dropout spacing. A simple ruler will suffice, as we're just trying to determine if it's intended for 126mm or 130mm hubs.

Nope...no rifling in either of the tubes, i sticker my finger inthere but couldn't feel any ridges inside.
It is 126 mm.
