An attractive new frame – developed to meet the needs of riders seeking a high performance bike constructed from quality materials and held to the ultimate standard of workmanship that is synonymous with Colnago. The structure is a unique, new monocoque design – with carbon fiber dropouts.
The CLX is a product that points to the favorable ratio of stiffness to lightness and comfort. Building on our experience with the V1-r, the concept of conceiving the design of the various tubes was simple. We found an oblique, oversized tube set that embraced a large bottom bracket area (with a standard Colnago ThreadFit82.5 system) and a conical seat tube for use with lighter and more comfortable 27.2mm diameter seatposts. Another important feature is the internal cable routing, which keeps the frame aesthetics absolutely clean. Eight sizes are available, all sloping (42s, 45s, 48s, 50s, 52s, 54s, 56s, 58), in four colors. The frame weighs only 950 grams.

The CLX fork is a carbon fiber monocoque design with straight blades. The base measures 1-1/4”, while the top is 1-1/8”. The most impressive detail is the conical crown-race made of carbon fiber – upon which rests the lower bearing of the headset. This design allows you to mount spacers up to a maximum of 28mm stack-height. The fork’s dropouts are made of aluminum for safety.
The CLX seatpost is made of carbon fiber with a light alloy head. The diameter measures 27.2mm – smaller and lighter than an oversized 31.6mm. It’s also more flexible, thus able to offer greater comfort to the rider on rough terrain.
The braking system on the new ClX is a traditional, center-mount type – centrally mounted on the front of the fork, and on the bridge which joins the seat stays in the rear. This allows ease of use and maintenance, and compatibility with all component manufacturers’ current groupsets.
A high-value option – the new CLX dropouts are a carbon fiber monocoque design, with a replaceable (internal) derailleur hanger. This offers advantages in terms of robustness, as well as significant weight savings. The drive-side dropout also has a provision for the passage of the rear derailleur cable for both mechanical and electronic shifting.
The Colnago ThreadFit82.5 bottom bracket system, the same used for the C60 and V1-r, is what you’ll find on the new CLX. Ernesto Colnago chose this system based on his assessment of all standards on the market. BSA is great for reliability, but combined with frames that have oversized bottom bracket shells or press-fit systems, none of the available systems met the requirements of reliability and durability needed for truly high-quality bicycles. Unwilling to compromise, Colnago has decided to take the best from both technical solutions: the reliability and practicality of a threaded bottom bracket (BSA), along with the width and rigidity that characterize the standard press-fit. This led to ThreadFit82.5 – compatible with all versions of Pressfit 86.5 bottom brackets, it adds two new cups in light alloy that are easily removable if necessary.
