2020 COLNAGO C64 FRAMESET AND FORK PKBK MATTE BLACK

This bike is still brand new. It was built on our floor as a bike, but we took the components off. It has never been ridden.



Introducing the New Colnago C64!



Get in touch with us, and we can order whatever size fits you best!



Colnago C64: completely handmade; tailor-made, it could

be said in Italy, with revolutionary tubes (larger, lighter, more

durable), the C64 is the fruit of more than two years of research.

Yet, it was designed based on an almost immeasurable history

of cycling innovation and success one which began in 1954.

The C64's tubes and lugs are made of the finest carbon fiber,

making it a unique frame in the world one that cannot be

compared to anything else. In the C64's design lies Ernesto

Colnago's knowledge and experience, gained from a lifelong

pursuit of cycling perfection.



The 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,

we'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.

Fork weight is 355gr.

With the same shape as the disc fork, the rim version houses the

pivots for the direct-mount brakes which offers plenty of tire

clearance. The fork length was increased by 5mm to be able to

accomidate larger tires yet still have a hollow upper structure, to

lower the weight but still retain the same stiffness and performance

as the C60 fork. Dropouts are now full carbon replacing the alloy

dropouts used on the C60.



The Head Tube:

While still retaining the same overall shape as the C60, the

C64's headtube features a new technology which allowed 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.



The Head Set:

Based on the experience we had with the Concept's headset,

we wanted to bring that technology to this model as well. So

we 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 capacty to absorb

road vibration, improving both handling and rider comfort.



Down Tube:

Starting with the design of the heavily shaped C60 downtube,

we revised the bottom portion, which is now a bit narrower to

match better with the rear triangle-for a perfect balance. To

increase the torsional stiffness and maximize the integration

of components, the downtube features a recessed bottle

cage area which creates two long ribs around the middle of

the downtube. Regardless of the fact that the C64 was not

designed to be a purely aerodynamic frame, the recessed bottle

cage gives a clear aero advantage over a traditional mounting

position. Cable stops for mechanical shifting are now located

on the downtube, in a tucked position behind the headtube.



Seat Tube:

Probably the most striking difference between the C60 and the

C64 is that the seat tube meets the seat tube lug to form a

single piece. This technical feature increased the stiffness of

the frame, while keeping the weight low. The monostay is no

longer straight either, but is conified to create the best possible

gluing surface. Of course, this means we now have 14 different

seat tubes for all 14 sizes!



Seat Clamp:

For a perfectly streamlined seatpost area, the C64 now

features a hidden integrated clamp. Instead of a top-loaded,

two-piece seatpost clamp, the C64 has a co-molded alloy bed,

with a single removable part tightened from the bottom. The

overall look is sleek, and the weight reduction is around 15gr

compared to the other style. The bottom-pull concept also

provides further locking strength as rider weights increase.



Bottom Bracket:

Designed around our proven ThreadFit82.5, which is basically

a PressFit with removable base sleeves, the bottom bracket

lug is now more complex than ever. The cable guide, which

was typically a bolt-on plastic part, is now molded into the

lug to save grams as well as to offer the biggest possible

radius for the best shifting performance. Another small detail

is the hex shape on the side of the downtube insert, which is

our datum point to check anything during the bonding of the

frame and, later, the QC process. Another striking difference is

the asymmetric insertion of the chainstays, with the left one

being much wider.



Rear Triangle:

Another key area where we completely changed our technology

is the chainstay/dropout area. The C64's dropouts are now

fully part of the chainstays. The one-piece construction allowed

us to lower the weight, add vertical compliance, and retain

the same lateral stiffness. The disc-brake frameset features

threaded12mm thru-axles and co-molded flat-mount brake

provisions. The rim-brake chainstays are a bit wider than the

disc version, to help keep the same rear stiffness due to the

lack of the thru-axle. This results in a very light but stiff full

carbon rear end. The replaceable derailleur hanger is the very

same, internally mounted hanger used on all our current road

rim-brake frames. The lightweight seat stay is designed around

very wide tires, and houses the alloy threaded inserts for

direct-mount brakes.



Tire Clearance:

While lower weight has so far been the key point of the new

frame, tire clearance is another important factor we had to

address while designing the new C64.

The frame has a clearance of a 36.5mm diameter at a 345mm

radius, which means you can use all 28mm tires with plenty

of room to spare. Brakes are the limiting factor here, so the

disc version has a bit more space.



Weight Comparison:

It is common to refer to the frame weight as the main factor in the

total weight of a bike, but that is not entirely accurate.

Compontents and details really matter on a bike frame, so we

worked dilligently to reduce unnecessary weight all around the

frame. For example, the C64 fork is now 40gr lighter than the C60

fork, yet stronger and stiffer. So, the total weight loss of the C64

frameset, compared to the previous C60, is around 205gr. The disc

version, thanks mainly to the new threaded thru-axle, and the full

carbon dropouts, is 270gr lighter than the C60 Disc frameset.



Stiffness:

The target for any modern frame is to increase

the stiffness, while reducing the weight

and adding as much vertical compliance as

possible. With the C64, we kept the same rear

stiffness, trying to replicate the appreciated

balanced performance of the C60, while

adding a bit of vertical compliance to give the

rider more comfort.



Weight:

Weight was never an obsession here in

Cambiago, but we are always looking forward

to improving our products in any direction.

Keeping the same safety standards we've

always used on our frames, which are much

higher than the common ISO-EN, we were still

able to reduce a lot of weight from the frame.

Here is the weight of the bare rim-brake

frames, without metal parts. Disc frames are

only15gr heavier than rim-brake versions.
