Back in mid to late 80s, the Bike Haus in Merced Calif specialized in tandems and the owners had a black Colnago tandem that they raced…got smoked by them a few times. I’ve seen other Colnago tandems over the years at tandem rallies and other events so I don’t think they are super rare.

I don’t see Specialized turning to Colnago or anywhere in Europe for a bike…USA or Japan. They already had bought Ritchey Mtn Bikes, so why not get a Ritchey road tandem which is superior to anything out of Italy in my not so humble opinion.

3Rensho would also be more to Specialized’s liking than a Colnago. For those interested,
there has been a 3Rensho tandem for sale on Craigslist in Bay Area, very cheap, like less than $500.00. Too big for me (23/20) otherwise I would have snatched it up.
