Firstly introduced in 2009, CX-1 immediately had a great success, representing a technological turnaround for our company. CX-1 model abandoned the traditional round tubes going towards polygonal tubes, marked edges and powerful sections. Stiffness was massively increased, making at the time CX-1 as the favorite bike of Colnago professional riders. For 2012 we’ve decided to make a restyling of that model, modernizing it with some of the solutions we’ve adopted in our top of the range M10 bike.
The main new feature is the ability to mount Shimano Di2 electronic group, in both versions (Ultegra and Dura Ace). In particular, unlike the M10 chassis, it will be possible to mount both Di2 and the traditional versions, regardless of specifications. To do this we have taken small technical and aesthetic steps that make the CX1 frame our most versatile and chameleon-like.
In the front, the most evident news is the adoption of a new steering zone with higher volumes and the adoption of headsets in different diameters 1″ 1/8-1″ 1/4. The CX1 new fork is of strict derivation from the M10, with squared sections and deep stiffening ribs.
Just behind the steering area, there’s a hole for the passage of the cable junction of electronic group. When using a conventional gearbox, a special polymer cap color-matching to the graphics frame closes this hole. The cable stopper braces, with the tension regulators, is removable with two M3 screws for the most possible clean design.
Placed in the bottom bracket there’s a new bb shell, a lot lighter than the original version and perforated to allow insertion of electrical wiring. Under the down tube, in this area, there are rivets for mounting the battery holder. The solution and the position adopted is the same as the top of the range C59 and M10. On the chainstays, with the same methodology used before, is the mechanical cables brace removable thanks to two handy screws. Finally, we re-designed the right rear dropout to allow the cable outlet of the rear derailleur in the electronic version.
