I just picked up a Pinarello cyclo cross bike. I'll add to this thread as I rebuild the bike. I've wanted to pick up a vintage cyclo cross for a while but they don't show up often. The bike is around the smallest I'll ride (a 56 center to top). I wanted it on the smaller side as vintage cross bikes tend to have a high bottom bracket. Also most, or at least the ones I've seen, don't take a very fat tire which makes sense since the pros ride tubulars. This bike, though, can take a 32c/35c tire which is a big plus.

I don't think this bike has seen a lot of use. The paint is in very good shape. And there is very little paint gone on the chain stay which suggests that it hasn't seen many miles. The bike came to me with a bunch of mainly Japanese parts and 3 x 7 gearing. The parts are fine but nothing special. I like the freewheel-a winner pro 12-28 7 speed that looks new--and the suntour bar con shifters.

I'll build the bike with different parts but I haven't decided on the build yet. I may go with suntour xc pro 3 x 7 and command shifters or I may go 3 x 7 shimano deore xt and bar ends. I like the idea of MTB gearing on a cross bike. Or I may "modernize" the bike by spreading the frame to 128 and going with brifters and a 46/30 crank.

The red tape the bike came with is ugly. This bike needs white housing and tape. I may go with a white rolls saddle and white time atac pedals as well.

I worked in a bike shop in the 80s and we sold Pinarellos. This bike has neat braze ons for the derailleur cables on the head tube (or perhaps the lug was cast that way), neat cut outs on the BB shell, nice fork tab reinforcements, and no chain stay bridge.

Edit: There is a Pinarello Treviso road bike. I figured this was the cross version of that bike based on what the seller told me but that could well be a mistake.

Nice find.

the "diving bell" cable stops are brazed on.

Rare bike. pretty cool.

I'm not finding a lot of info on the Treviso cross even though the catalogs from the 80s are available. The Treviso cross doesn't seem to pop up in the catalogs. One of these sold as a repainted frame on eBay which is a dead ringer for my bike. In the 1989 catalog, the cross model shows up but it's different and a later model than mine. It has Oria tubing and the diving bell has disappeared for a more conventional set up.

I think Old Fireleg might know a bit about these.

I don't think the model you're looking for is Treviso - that was the Italian city where Pinarellos were made. (Yes, there was a Treviso model, but that was a road bike.) I thought the CX bikes had a model name, but either I can't remember or they didn't.

The Cross model in the catalog looks a bit later than yours, as it has under BB cable routing and Oria tubing.

Like it a lot.

This was sold to me as a "Treviso" cross but I reckon you could well be right and the Treviso on the seat tube just refers to the city where the bike was made. I thought it was the Treviso cross version of the road bike based on the seller's description and the little I read about it on the web.

This eBay listing was also sold as a "Treviso" cross. I dunno if the seller was right but the seller does give what he or she believes to be the back story to the bike:

The pics of the bike are a dead ringer for mine other than the color but the bike has been repainted.

have an '85 treviso with shimano 105 brakes. biggest tires i can fit are a "28 up front and a "25 in back. heavy but sturdy.

Some thoughts:

Pinarello decals are notoriously flakey. Yours don't look in too bad condition - which makes me wonder if they are replacements. To back this up, the seat tube decal is the 'split' version that made room for the second set of bottle cage mounts, which your frame doesn't have. Edit: I just notice the 'Cross' model above has the split decal with only one bottle mount, so disregard that. I guess there's no need for two bottles during a CX race.

Along with the single bottle cage mount, the cable guides on top of the BB shell would suggest a late 70's/early 80's frame, I believe. What's the serial number? The early 80's format would be X### (X=letter, #=number)

Old Fireleg

What seems certain is the 1980-88 interval. '80 (short headtube's lugs), '88 ('89 catalog with Oria tubeset + old styl columbus decal) I think considering this link
https://www.speedbicycles.ch/velo/42...ross_1981.html
that the starting point is more '82 but even more '83. (The palmares sticker can also be a retrofit) You have already asked the magic question. If we get a response, we will be able to narrow down the production date's interval.
(It is surprising to me that none of the specimens that arose have a chainstays bridge.)

bikemig 

Very helpful. It's likely 1985-1986. The serial number is LLNNN which according to this very helpful thread that both of you contributed makes it 1985-1986.

Thanks to P!N20 and Old Fireleg for all the helpful info. Also--and I don't know why I hadn't noticed this earlier--but the sticker is a tretubi one. Plus the wrong sized seatpost was used. This is a 26.8 which likely makes it aelle tubing (or perhaps cromor?). The sticker does not say aelle though but columbus stickers are a bit of a mess.

Also could columbus SP take a 26.8 seatpost? I've seen one bike with what I am fairly certain was columbus SP that took a 26.8 seatpost.

The bike has all the nice details of a classic Pinarello. The fork has nice reinforcement tabs. My guess is that the fork and stays are Falck or something else pretty decent quality.

Old Fireleg

Yes, this '85 -'86 seems perfectly acceptable.
The maximum seat post diagonal of the SP tube is 27.0 mm. It may be less than that, but I don’t think it’s too common to be further narrowed to 26.8. But there may have been special considerations at CX. (SP was used for road frames 59 cm and above, for CX I don't know what the method was.)
Returning to the name. At the Italian manufacturers, with the exception of ALAN, the CX bikes were in fairly peripheral status, at least according to the catalogs. If even in ’89 he was just given the name “Cross,” I don’t think he had any other fantasy name before, but that’s just a guess, of course.

This is a good summary of the various Columbus tubing sets:

https://www.equusbicycle.com/bike/co...umbuschart.htm

One thing I am not certain of is whether the aelle tubing should be on the sticker or not. I had thought--perhaps incorrectly--that if the bike had aelle tubing that would show on the tubing sticker.

The left hand of the sticker is very hard to read as it's beat up but you can make out Tubi Reinforzati. I thought reinforzati meant double butted?

super cool

So a little bit of sleuthing helped me figure out the tubing. I'm not that familiar with Columbus tubing stickers and this thread really helped me out:

https://www.bikeforums.net/classic-v...-question.html

The bike is Tretubi SL or SP. It would not surprise me if it were SP given that this is a cyclo cross bike designed for being raced on rough stuff. I don't know the tubing for the forks or the rear triangle but I know that Falck tubing was often used by Italian manufacturers with "tretubi" bikes. The mystery to me was why a 26.8 seatpost fitted the bike and not a 27.0 or a 27.2 which is what I would have guessed for SL or SP. But maybe the ears were pinched or maybe the tubing wasn't reamed out properly. Thanks to T-Mar for his help in figuring out this tubing sticker.

Here are the stickers on the bike:

Many CX frames continued to use derailleur cables routed over the BB shell, longer than their road stablemates, as it was less prone to the mud fouling common in CX races.

Hello T-Mar, sorry to misuse the thread for a personal message but as a "junior member" I can't send you a private message. We emailed 5 years ago and I wanted to ask you a question, but the address I had for you in 2015 no longer works. Would you mind sending me an email at "wild" at "music", then a dot, then "mcgill", then a dot and the first two letters of Canada, so I can reply? (Sorry to make the address obscure but I don't want it to be stripped by the forum software or harvested by spammers.) Thanks - Jon

I'm still thinking about the build and whether to go 3 x 7 or modernize the bike by spreading the rear triangle to 130 mm and running "modern" gearing. I'll run 32c tires once I pick out the wheels.

But this bike can take big tires. I mounted up a set of wheels with phil wood hubs, mavic mod 4 rims (these are seriously wide rims), and Schwalbe marathon 700 x 35c tires. These tires measure 36c on those rims. I was surprised but they fit. I had thought that vintage cross bikes--by and large--did not take large volume tires. This one does.

Found this thread (and bikeforums) via google because I've acquired the same frameset and was surfing the internet for info and build inspiration. Where did you end up with the build?

bikemig 

It's still in the build queue! I've been too busy with life projects. I know I want to use the 46/30 IRD wide compact double as I have it in hand. I'll use Tektro 720 cantilevers because I think they work great.

For the gearing, I'll go 2 x 7 as I have a suntour winner 12-28 freewheel that would mesh nicely gearing wise with the 46/30 double. I have an almost complete suntour xc pro group that came off a top end Bianchi cross bike, a Bianchi equinox, that I plan on using with this build.
