Colnago Frame C64 Disc Fm Ta Dual Tfs 45s Pjwh 2019

Fork - The C64’s fork has been fully redesigned, with an external rib-shape to give the rider more comfort (front stiffness) but also to increase the ride-quality (side stiffness). To increase the stiffness and strength, they’ve created an internal rib in the steerer tube, which also holds the nut for the top cap and eliminates the need for an expander-plug. The C64 Disc fork will feature a C/D steerer tube shape, where the brake housing can run from the stem – for a neat assembly. The thru-axle, while still 12mm like the C60 Disc, is now a threaded system to further reduce the weight of the bike.

Headtube - Lighter and stiffer thanks to the reduced thickness, the unidirectional fiber and the special inner rib. 

While still retaining the same overall shape as the C60, the C64’s headtube features a new technology which allows us to reduce the thickness and lower the weight. The shape was also revised to increase side stiffness. As was the entire frame, the headtube was changed from an outer 3k carbon finish to a lighter UD finish.

Headset - Based on the experience they had with the Concept’s headset, they wanted to bring that technology to this model as well. So Colnago revised the upper cups, which are now made of a special polymer composed of carbon fiber and a special mix of nylon and elastomers. This feature offers the additional capacity to absorb road vibration, improving both handling and rider comfort.

Downtube - The stellar section and the reduced width increase the torsional rigidity.

Seat Tube - Single piece monocoque, to make the frame more stiff without increasing weight.

Seat Clamp - A more elegant line, with the seatpost locking system completely hidden.

Seat Post - Based on the shape of the V1-r seatpost, the semi truncated drop shape adds a bit of aero performance, while giving better vertical compliance compared to the previous round 31.6mm seatpost.
