Need help identifying this Guerciotti
 

I just won this auction for a Guerciotti and could use some help identifying what year and model it is. Also what kind of steel tubing since the seller did not know nor is there a decal. I will be able to do some more research once I receive the frame and can read the serial number, but I was hoping you guys could give me a head start. Thanks!

It's a re-paint, that's a start. He and others sellers have been selling that brand for a number of years now on e-bay. Some have a tubing sticker bt in many cases the tubing is only implied, stated or not. There's a stash of Guerciottis somewhere back in the old county. The beauty is, that on account of Guercotti's no account of exact history, record keeping, tractability in builder source, it's an ideal candidate for selling as NOS, repainted as stated or not... or the like.
It's not an SLX frame and can't possibly be a TSX. The years alone belie these possibilities as the man stated the spacing's been spread which is written testiment.
Theoretically narrow spacing could possibly exist on an SLX frame, statisically a virtual near impossibilty given the year. All this simply judging by his words, the year/spacing.
The fork crown; that design wasn't used on many SLX frames which more often than not had semi-sloping. SL frames used mostly the flat, "traditional" crowns as did both Aelle, Chromor & Gara. The crown's cap been replaced too I suppose. Campy bits are standard issue or can be retrofitted, not at all telling.
Checking for the riffling would show its being an SLX, it would not distinguish an SL from the others. Seat post diameter ID, best indicated by what S.Post fits can tell you that it's SL. Bear it mind that the majority of more modern chromoly bikes use 27.2 so why not use one off another bike to check if not, you would oherwise need to measure carefully with a caliper. I've little confidence that it'll be easily done without an actual seat post. ODs on posts are easier to meas. than IDs of tubes. Calipers can be tricky. Remember, only a few fractions (.2 mils) at times can be a dec. factor even when meas. exactly, a frame from one company could've chosen a different seat tube or swedged size than another. 27.2 shows it's SL whith fair accuracy. If it's considerably narrower, it's most likely not. I hate using that criterea; too many exceptions due to chosen bits of tube irrespective of what the bike was sold as, often a tube or so would be dif. which was the BUILDER'S choice.
It's a nice frame, worh every penny; The OE paint was often not the greatest on many Italian bikes. It's got nice work, it's not typical of Chromor but it could be. My bet is...it's Aelle. Those who ride such framed bikes describe them as "sweet".
Chromors are fine too, those I've ridden and can't tell the difference. SL speaks for itself. You were wise to buy the bike and not buy into the notion that tubing model is the be all and end all. Leave that for big fat showoffs such as myself.

Old and New, thanks for the info. cb400bill, thanks for posting the pics (new Mac and I haven't quite mastered all the ins and outs yet)

I was planning to try a 27.2 seatpost when it arrived and then go from there on determining seat post diameter. The main reason I bought it was for it's rather rare (at least by today's standards) geometry. 60 cm seat tube and a 56 cm top tube. Works great with my build (long legs, medium torso).

Over the BB cabling and braze on shifters would probably put it in the early 1980's

That bike is a mid/late 70's, long Campagnolo dropouts, nutted brakes so probably Columbus SP. The 56cm seat, 60cm top would suggest to me that it was a custom build.

those dimensions are more common than not especially in the early '80s and before, typical Italian geometry. By the very late '80 actually even later, tope tubes were more or less equal the the STs, depending on brand. Most older ones had short TTs.

Grab any seat post that's handy. Shops have meas. guages, tube things with steps, much easier than fiddlin' with a caliper. Any LBS oughta get a kick outa that frame and will oblige.

Doesn't really match up with anything over at CR

I flipped his st/tt measurements, my mistake (coffee please). Disregard my "custom" designation but I stand by a 70's not 80's bike.

Here's a link to a 1975 on Wool Jersey Gallery

Could very well be a late 70's bike., but not early. The braze ons would most likely rule that out. The lack of engraved seatstay caps is a bit unusual for a Gooch, as least the few I've seen.

Good one, the SL thing, just maybe:thumb:

It has been repainted so braze-ons could have been added then. I have a 73/74 Masi and a 76 Spezzotto that have shifter bosses and a set of bottle bosses (no tt cable guides) so the the only thing that points later 70's is the tt guides. I haven't seen long rear dropouts on a 80's Italian race bike myself.

by the way, OP, nice score for $200, well done!

Wow, thanks guys! You are all a wealth of knowledge. I can't wait for it to arrive so I can build it up and see how she rides.

Ok, I got the frame today! I am very pleased with it in person. Super smooth Campy headset that I don't think I will even service for a while. Seat post is 27.2. Doesn't quite feel SL light, so I am going to go with SP. Doesn't really matter to me anyway. It fits like a glove and that was the main reason I bought it.

SL or SP, both good , poss. Aelle, probably not. Matters little to you, even better !

Thanks for letting us know. It's a really nice one !! Salud !
