Developing the ThreadFit 82.5 Bottom Bracket for the Colnago C64

From our friends @Ceramic Speed’s blog

“Colnago. The name carries history. It is synonymous with craftsmanship and visionary passion. It is therefore not surprising that the name to some epitomizes the art of frame building. The Italian brand is certainly special, of that there is no doubt.

When Ernesto Colnago founded the company in 1954 he had put his own racing ambitions aside. Working as a mechanic for some of the most prolific racers of his time, riders like Eddy Merckx, Marino Basso and Rudi Altig, helped him to fine-tune his ideas about frame design during the brand’s early years.

Since then, Colnago has established himself and his brand as a household name in the cycling world, having been the proud bike sponsor of no less than 73 professional teams so far. The Italian has also successfully positioned the company at the forefront of the industry, at first with lightweight steel and later with iconic aluminum frames.

In recent years, though, the introduction of carbon as a material for frames has not only disrupted the market but has given it a new direction. Numerous brands have since challenged the boundaries of frame design.

Colnago, however, stayed true to himself and his principles. At 86 years of age, he is still the leader of his vision. He continues to push limits while maintaining a uniquely recognizable style. The C64 is proof of that.

Bringing a new development to life

The Colnago C64 was launched to mark the 64th anniversary of the company. It is presented as the (r)evolution of a species. With a nod to its predecessors, the new top-end race bike maintains recognizable lines, whilst receiving several new developments. It offers an increased vertical compliance, greater tire clearance and also weighs less, due to the revised design of the trademark lugs and tubes.

That’s not all, though. One of the main differences lies within the bottom bracket lug. Designed around Colnago’s ThreadFit 82.5 the new lug is more complex than ever.

To develop the bottom bracket lug Colnago partnered with CeramicSpeed. Taking pride in building high-end products by hand in their respective facilities this collaboration was an obvious one for both brands.

The goal for the technical designers was to create a bottom bracket that would combine the reliability of threaded cups with the benefits of wider shells, typical for PressFit systems. In conjunction they developed the ThreadFit 82.5 Bottom Bracket, a bottom bracket specifically designed for and exclusively used in the C64. The whole process was completed in less than four months: Precision engineered.

The C64’s unique bottom bracket cups are adorned with the logos of both brands, to underline the collaboration. All cups are selected and examined before the production of the ThreadFit 82.5 Bottom Bracket. The bearings are made up of the highest quality races in combination with CeramicSpeed’s unrivalled ceramic balls, seals and grease. All parts are carefully chosen and controlled, before being assembled by hand at the brand’s headquarters in Holstebro, Denmark. It is available for Campagnolo, Shimano, Sram and FSA, Rotor and alike.

Another chapter opened

Colnago has opened another chapter in its long and versatile history, with the launch of the C64. The development of the bike is a masterpiece of how excellence is brought to life. It is by no means a visionary one, rooted in the tradition of crafting timeless high-end bikes. And it would be an understatement to say that having been chosen to be a development partner for this anniversary project has been our honour.”
