The company says the C64 is only slightly stiffer than the previous model at the front and bottom bracket, but has the same stiffness at the rear triangle.Ĭolnago continues to use its ThreadFit82.5 bottom bracket with the new C64. There’s recessed section on the down tube for the front bottle cage that provides a bit of aerodynamic gain. It’s more likely you’ll get it out with no damage to the frame. There’s also added room in this area, which is handy if you drop your chain. The down tube is narrower especially at the bottom bracket lug to cut some weight. Another new feature of the C64 is its asymmetrical chainstays, which address the different braking and pedalling forces on the frame. The C64 can accommodate all gruppos with its finishing kit. The C60 came in two frames: one for mechanical groupsets and one for electronic ones. While the C60 featured a 3K carbon finish, the C64 has a UD finish. With the C64, many tubes have star ends and the head tube has a recessed section to save on weight. On the C60, the lugs could accept fluted, star-shaped tube ends. That model had fluted tubes, which were rounded at the ends to mate with round lug openings. Since the C59, the tube shapes have been getting more complex. Riding the Colnago C64 in Saguaro National Park, Arizona. I’d say that amount of clearance is just keeping up with current trends for more rubber on road bikes. They’re clear that they mean an actual width of 28 mm not merely the nominal designation. The company says the fork and frame can accommodate 28-mm-wide treads. This increase allows you to run wider tires. The distance from the axle to the fork crown is 5 mm longer than on the C60. A rim brake fork, according to Colnago, is 355 g. You’ll notice indents on the sides of each fork blade. On a Size 50 sloping frame (roughly the equivalent to a traditional Size 54), the C64 frame, excluding the fork and rear derailleur hanger, is 186 g lighter than the C60. Still, the C64 is lighter than its predecessor. “It’s always focused on making the ones that ride the best, making them robust so they last a long time and making them easy to maintain.” “Colnago has never been known for making the lightest frames,” said Kevin Clark of Colnago North America. While the new frame has replaced the C60, it’s helpful to look back at the previous model to see how the company has improved its high-end, made-in-Italy bike. The “64” in the name is for the 64th year of the company, which Ernesto Colnago started in 1954. It’s not a speedy process-it takes 12 to 15 hours-so Colnago can only make a few C64s per day. The tubes are cut to length and fitted to the lugs, in a similar way to steel-frame construction, in Italy. The C series, which started in the early 90s with the C40, sports a carbon-fibre tube-and-lug construction. I had a very specific machine to check out: the new Colnago C64. But more to the point, like so many North American cyclists, I had gone south to ride. The desert really doesn’t hold the previous day’s heat so it was below zero. Why was I freezing in Tucson, Ariz.? Well, it was a Tuesday morning in January.
