DESCRIPTION

Introducing the New Colnago C64!

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.
