Price Porn: Colnago Pantographed 6 pin Crankset, 1980's, RARE, NR


Sold: $531 including shipping

Attention vintage Colnago collectors. Here is one of the great Colnago rarities. It is a six pin pantographed crank set in 170 mm length. These were made by Ambrosio. Gearing is 53x36!! Bolt circle diameter is 120 mm. Don't ask me where you will find extra rings! I bought these new in the early 1980's and they were used on a Colnago Super. These cranks will work fine with a Campagnolo bottom bracket or any other Campy taper bottom bracket with a 115 mm or so length. The condition is very good. The cranks could use a good polishing. The rings are in very good condition. Plenty of miles left. The paint in the engraving is decent condition but could be easily redone for your Colnago show bike.

The last photo is from flickr user GTS753, who is apparently lucky enough to own two of these cranks; his 42/52 version can be seen here.

Campy Oldy claims that only a couple were made but that seems unlikely. Still, they are indisputably rare, and given the desirability of any Colnago panto parts, maybe this isn't such a huge price. Better photos would likely have boosted the price and conveyed more about the condition.

I couldn't find evidence that Ambrosio made a non-Colnago version. Has anyone seen one?

Nice crankset with extra examples from one of the the major Australian "Glitz Kings" and mounted on a heavily over-restored Mexico Oro.
These cranksets come up for sale at least once a year and are always panto'd Colnago. They're most always purchased by the same Glitzers.

An NOS example of this crankset, in its original Colnago box, and with the more desirable 42T inner ring, sold a few months ago for over $1,200. The buyer was another very nice Aussie Glitzer. (Ich bin ein Glitzer zu!)

The Mexico Oro is part of my collection and I may take issue with the 'over restored' comment by anon. There were a few small items that needed correcting, but basically the bike arrived from Germany in this state.
The Ambrosio crankset came with two vastly different geared smaller chainring, either a 36 or a 42. The short stubby crank armes allowed the smaller gear ratio. Chainring bolts were not stamped and I have never seen a crank dustcap that has been marked Ambrosio. Campy ones fit as do the Campy crank extractors. The Ambrosio five arm cranks share the same left crank arm with the 6 arm. These five arm pantographed cranks can come with Campagnolo stampings or without. It appears that these were removed from the Campagnolo production line at some point and then milled, pantographed and high polished.
These are not as uncommon as you think and were offered as a factory option around 1980 and were even in the factory catalogue. They might appear twice a year on ebay.
