{"product_id":"colnago-c64-disc-frameset","title":"Colnago C64 Disc Frameset","description":"\u003cp\u003eThe alchemists of Cambiago would have been forgiven for  resting on the plaudits of their Colnago C60. It got love from every quarter. But  as cyclists and designers, rest isn’t easy; they’ve trained themselves to keep  going. No sooner was the C60 established as a super-frame, they made it their  new benchmark and decided they needed to exceed it in as many ways possible. That’s  what the C64 does.\u003c\/p\u003e\n\u003cp\u003eThey just wanted to make it lighter, stiffer, more  comfortable, more aero, better looking,  easier to work on, and stops better. The  proverbial going to eleven. Which is what they did, making the C64 the new ten,  the new essence of their perfection, as best they can distill it today.\u003c\/p\u003e\n\u003cp\u003eOf course, it’s made from carbon-fiber tubes and lugs. The  joinery allows for better compaction, greater strength, better tuning of ride  qualities. The tubes are formed with stainless steel inner and outer molds,  which means they can remove the inner mold at the end of the effort and have a  tube that is as smooth and even and good-looking on the inside as it is on the  outside. The head tube is a single piece for strength and light weight, while  the seat lug is designed with an internal binder for security and beauty and  weight savings; a single 4mm hex head key does the tightening. \u003c\/p\u003e\n\u003cp\u003eAnother cool innovation, which follows a pattern with many  of their other design innovations is the rear derailleur hanger. It’s mounted  inside the right dropout so that when it deforms or breaks under stress, it  doesn’t affect the carbon-fiber dropout at all. This is of a piece with their  ThreadFit 82 bottom bracket, where you can replace the threaded inserts if they  wear out or get damaged, though you still press in the bearings for weight  savings and stiffness. It’s also the kind of thinking behind the headset, of  which the body incorporates a special mix of carbon fiber, nylon, and  elastomers, taking the edge of vibrations while still precisely tracking. \u003c\/p\u003e\n\u003cp\u003eThe seatpost is designed to integrate with the seat collar. It’s  a truncated cylinder that is both aero and comfortable—aero because of the  leading blunt edge and comfortable because the smallish diameter and  Kamm-tailed style shape allows for rearward flex. The shaft is carbon-fiber for  vibration-damping and weight-savings, while the forged aluminum head, hidden  behind the paint, is light and durable and easy to micro-adjust. \u003c\/p\u003e\n\u003cp\u003eAerodynamics they considered as part of the package, but not  a defining feature. They wanted aero, but not at the expense of ride quality. You’ll  see that the head tube, the fork crown and head tube juncture, the fork crown,  the seat post, and the down tube are tugged to make them slice the air better,  but not dramatically. The most important tube shape might be that of the  downtube, which is wider than it is tall and slightly lowered. This helps moves  air around the water bottles and seat tube better, but it results in a better  ride quality than a more dramatically-shaped tube.\u003c\/p\u003e\n\u003cp\u003eThe downtube shape also contributes to torsional stiffness,  as do the chainstays and the seat tube. The stays are set as wide as possible,  while still allowing for chainrings and generous tire clearance. They are also  asymmetric, with the left leg lower than the right to better counteract the  stresses that result from the right-side driving the rear wheel. The seatpost  is as large as they could fit without impinging on tire size to make sure the  bike was as rigid as possible for pedaling. The final part of the stiffness  equation is the fork. They started with a tapered 1 1\/8” to 1 ¼” steerer for  stiffness. They also set the legs out a bit wider for both strength and to  better fit direct-mount brakes. \u003c\/p\u003e\n\u003cp\u003eIn terms of comfort, there are several things both obvious  and subtle that make the bike more compliant. You can see that the top tube is  flattened toward the seat tube for comfort, and the seat stays are fairly thin.  The seat stays also have mounting points for direct-mount brakes. The seatpost,  too, has a shape that allows for some give. But they go beyond. The seat tube  lengths have changed a bit from the C60, allowing for a little more post to be  showing for what is otherwise the same size. The fork legs taper dramatically  so that they can move vertically some without compromising steering. They also  made room for 28mm tires, so you can put on your Roubaix tubulars and still  have room for gravel and muck to pass through. And don’t forget the elastomers  formed inside the headset.\u003c\/p\u003e\n\u003cp\u003eThe geometry is pretty much unchanged in key areas. This is,  after all, a Colnago, and ride quality is paramount. The head and seat tube  angles and fork rake are all unchanged. These are essential elements and there  was no reason to tweak what is so cherished. Bottom bracket drop is unchanged  on most sizes. Chainstay lengths have been adjusted to make room for 28mm tires.  Other than that, little is different. \u003c\/p\u003e\n\u003cp\u003eOne last improvement Colnago made to the C64 was cable  routing. No longer do you have to choose between electronic or mechanical  routing. The bike has internal routing for both, and comes with the stops and  plates and plugs necessary so you can choose which one you want at any time. \u003c\/p\u003e\n\u003cp\u003eWeight for the C64 is 900g for an unpainted size 50 sloping,  with a 355g uncut fork.\u003c\/p\u003e\n\u003cp\u003eThe Colnago C64 comes with frame, fork, headset, seatpost,  small bits and pieces for cable-routing and such. The included seatpost is  350mm long and has 15mm of setback. There are accessory 0mm and 30mm setback  posts available if the standard doesn’t work. You’ll need to supply the  direct-mount brakes. If you go electronic wired, the battery mounts internally.\u003c\/p\u003e","brand":"Colnago","offers":[{"title":"PKBK \/ 45s","offer_id":43510177038380,"sku":"F64F05KB","price":5500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/colnago-c64-disc-frameset-3084275.jpg?v=1771301413","url":"https:\/\/ricycles.com\/products\/colnago-c64-disc-frameset","provider":"RA Cycles","version":"1.0","type":"link"}
