1976 Colnago Super

Here's another Colnago Super for your enjoyment.... a 1976 model. Very neat and all original.


















The Ernesto Colnago pantographed chainring is a real feature. A truly classic Italian steel bicycle that is beautifully maintained considering its age of 41 years.

Thanks to Anton Bicycle for the images.

Safe rides,

Quill stem with 31.8mm clamp

The 31.8mm quill stem is an evolution in traditional quill stem design – simple yet clever. Cyclists have always wanted a classic looking quilled stem that could accommodate 31.8mm handlebars without having to use those ugly adapters. This is a very traditional looking stem that will compliment any vintage bike that needs a 1″ threaded headset.

Factory 5 Titan stem - 31.8mm clamp area



It’s incredibly light at 270g and will finally allow you to choose from the wide world of handlebar possibilities that have a clamp diameter of 31.8mm. The stem is made from 7075 aluminium and has a removable faceplate that is held in place with two stainless steel screws. 

The removable faceplate is a bonus as it enables you to remove the handlebars without disassembling your entire handlebar setup. It also allows you to fit the bars with ease as sometimes a traditional quilled stem is difficult to slide around the handlebar curves enroute to the clamping area.

The overall height of the stem is 150mm which allows for a height of 100mm above the minimum insertion line. This is a really good extension height considering that older cyclists prefer a more upright seating position and may require a higher set handlebar - this stem easily allows for extra height.

The stem is available in either a high silver polish or a deep black anodized finish. It is available in two extension lengths depending on the brand you by – extension lengths are 80 or 90mm only.

The stem is similar in styling to the Shimano 600 AX stem of old but as mentioned before it now provides you with a huge range of modern drop handlebar options with a 31.8 clamp area, especially modern road handlebars with short drops which are very comfortable and practical.

As with all cycling gear the price range varies dramatically across differing brands as below: 


       JRI Rigg stem          US$139.00           silver/black        90mm extension only



          Factory 5 Titan stem         US$ 99.00         silver/black     90mm extension only


            Senqi stem             US$ 30.00          silver only            90mm extension only


         J & L vintage classic   US$ 38.00          silver only         80mm extension only


I’ve just bought one for a 1990’s Colnago Super build and will post some pics when it’s done.

A quilled stem well worth considering that will increase your choice in modern handlebar options.

Safe riding.

1989 Colnago Master Pui

Here is something very easy on the eye - a 1989 Colnago Master Pui. 

The Master Pui is a variant of the Master series of Colnago steel framed bicycles. The Pui versions were introduced from 1988 onwards and are highly prized collectable bikes.

Ernest Colnago started making steel framed bikes in 1952 and was a bike mechanic for Faliero Masi in 1955. The Colnago brand continued on with great success and in 1963 was a big part of the Molteni Racing Team that developed the cycling legend Eddy Merckx.

The Colnago Master series of steel bicycle frames are still manufactured today, although they are a very rare sight on a Sunday morning ride.

Enjoy this one.....chromed lugs, chromed fork, built with Columbus nivachrome 'Gilco' shaped steel tubing, and dripping with a Campagnolo C Record groupset including Delta brakes. The pantographing on the frame also makes it a standout model.

























If you have an interest in Colnagos here is a great photo titled 'The Colnago Rainbow' that includes 6 Colnago steel framed bicycles manufactured between 1974 to 1982 (ROYGBIV).

De Rosa Nuovo Classico

Although it's not a real vintage bike, this De Rosa Nuovo Classico is of vintage heritage and well worth a look. 

Fitted with a Campagnolo Record 11 speed drive train and a Campagnolo Eurus wheel set this example is sweet on the eye and very desirable for any cyclist with an interest in steel. The frame has chromed lugs on the head tube and a chromed chain stay - typically classic. 

You can still have a vintage styled steel bike with the absolute convenience and reliability of a modern drive train.

I love steel.....but for me the drawcard to this frame is the De Rosa pantograph work on the fork crown (image #6). De Rosa have faithfully maintained this beautiful element in their steel frames - something that other manufacturers have simply forgotten.

Well done De Rosa!!


















Thanks to 'Ciclicorsa' (Italy) for the images, have look at their impressive website for more De Rosa models.

Safe riding..
