Wonder if someone could help me ID this Pinarello. The original Campy components have been replaced with Dura Ace. I'm being told it is 85ish Treviso, but I am not sure. Frame seems to be in quite good shape. Would a serial number off the BB be helpful or not? Seller is asking $800. Thanks for any help!

Same bike as in this post.

That's correct. Was the Treviso model not labelled near the front of the top tube like other Pinarellos? And what about the year?

It has been repainted I'm sure so it is hard to tell. Sometimes all the correct decals aren't there. If you trust the seller, a forum member here, buy it if not pass.

The only model that this one can be is a Record, '85 or '86. That was the only one (save Montello) that had both chainstays chromed. Montellos should also have chrome seatstays, among other things. The original finish should have shown chrome seatstay caps, covered by the repaint. The repaint decals usually don't come with the model designator for the toptube.

Well, if the consensus is that this bike has been repainted, how do we know that the fork wasn't chrome at one time and has been painted over, which would make the original model possibilities different?

imo, the jury's out on a repaint-

The first that I recall that the model name decalling was shown on the top tube was approx. 1985, concurrent with the introduction of the Montello.

I am also of the belief that it's most likely a Record Equipe/Special but I'm voting for an late 84 original manufacture date.

Dating Italian bikes, esp by small volume manufacturers (as Pinarello was in the 80's) isn't ever going to be an exact science.

Precise model year delineations don't generally exist at all but rather a new model will see introduction at most any time during the year and construction /cosmetic details will often vary from frame to frame and batch to batch as the builder sees fit, with distributor demands, and with subcomponent parts availability and supplier costs.

Any given model will then gradually ,steadily and sometimes sporadically evolve over time, often even taking on a different position within the product line over the course of its production span .
Even decalling and model designations for the same bike can sometimes change within the same model year.

IMO, the best that you can do is unearth a preponderance of frame details and determine their associated timelines to make a calculated, educated assement of any given frameset that hasn't been firmly documented.

Even then , frames and bikes were commonly held over in inventory thru the calendar year before purchase & delivery to the original owner.
Also, a few major importers typically brought in their framesets bare & unpainted, (sometimes not even affixed with braze-ons and chrome details) and would have them detailed, finished & outfitted in-house.
Such a frame might have had a mixture of details and decalling spanning a year or more and sold as current inventory.

caterham, thanks for all your insight and comments. Relative to this particular bike, can anyone tell me whether Pinarello has a reputation for excellent duration of their original paint and decals as this bike appears extremely clean after 20 years or so, if it hasn't been repainted. I really don't know the bike's history, don't know how much it's been ridden. I've been told it was recently in the hands of a collector. I'm also trying to figure out why and when the Campy was removed and replaced with Dura Ace. That's hard to understand as well.

By the bridge between the chainstays it is not a Montello. They lack this.

The experience I've had with my '87 Montello that I bought new as a frame only is that the decals have a lowsey thin clear coat and over the years don't last. The chrome however is in great shape after 20 years.
As for D/A instead of Campy? I chose D/A because at the time they had the first indexed 7sp. And it worked. Campy Syncros that my bike shop owner used on his ride would always give him fits every time we rode together. He made me pronounce it " Dur-atch-ee" however.
