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.

Factory 5 stem with Ritchey Classic 31.8mm handlebars

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.
