Colnago has been building race bikes in Cambiago, Italy since 1954 — longer than most of the brands it's competed against have existed. The C64 Disc is the current expression of that lineage: a handmade carbon road frameset built using the lugged construction method that Colnago pioneered and has refined through the C40, C50, C59, and C60. It's raced at the highest level of professional cycling and available here as a frameset for riders who want to build their own. There are faster bikes by the numbers and lighter frames by the gram. There is no road frameset with more legitimate racing heritage than this. Lugged Carbon Construction — Colnago's Singular Approach While the rest of the industry moved to monocoque carbon construction, Colnago stayed with lugs. The C64's carbon tubes are bonded to carbon lugs at every junction point — the same structural philosophy that produced Colnago's most celebrated frames, now executed in high-modulus carbon rather than steel. It's not a nostalgic choice. It's a deliberate engineering decision that gives Colnago's builders precise control over how stiffness is distributed through the frame: stiffer at the bottom bracket and head tube, more compliant through the tubes where a rider feels vibration over long days in the saddle. The C64 updates the C60's lugged construction with UD (unidirectional) carbon replacing the heavier 3K weave on the outer layers — reducing weight while maintaining the structural integrity of the bonded joints. Internal ribs have been added throughout for targeted stiffness, and wall thickness has been reduced across the frame. The result is a bare frame weight of approximately 900g for a painted 52cm — competitive for a lugged carbon design and a meaningful step down from the C60. The asymmetrical chainstay design is worth understanding: the left chainstay is significantly wider than the right, improving power transfer from the drivetrain side while preserving vertical compliance where the frame meets the road. The dropouts are fully integrated into the chainstay construction — a one-piece design that reduces weight at the rear axle interface and eliminates potential failure points from bonded dropout inserts. Disc Brake Architecture and Frame Details The C64 Disc uses conventional 12mm thru-axles — a clean break from Colnago's previous proprietary Hexlock system and a welcome one. Standard thru-axles mean serviceability anywhere, compatibility with any disc-specific wheelset, and no special tools required in the field. The disc model weighs just 15g more than the rim-brake C64 — essentially the same frame with the additional hardware required for hydraulic braking. Internal cable routing handles both mechanical and electronic drivetrains. The frame ships with the stops, plates, and plugs needed for either system — you choose your drivetrain at build time without any frame modification. The C64 Disc fork routes hydraulic brake lines internally through the steerer, keeping the cockpit clean and protecting the lines from trail debris. The ThreadFit 82.5 bottom bracket standard is one of the C64's most considered engineering choices. It combines the oversized stiffness of an 82.5mm shell with a threaded interface — you press in a replaceable threaded sleeve and use any standard BB86/BB86.5 threaded bottom bracket. The result is the quiet reliability of threaded installation in a stiffer shell than a traditional 68mm English BB. No creaking, no special tools, full serviceability. Carbon-elastomer headset cups absorb vibration at the head tube before it reaches the cockpit. It's a small detail that makes a real difference on chip seal and rough pavement over long rides, and it's the kind of attention to ride quality that shows up throughout the C64's specification. What's Included in the Frameset Colnago includes more with the C64 Disc frameset than most brands provide. The C64-specific carbon stem is included — an integrated design that routes the hydraulic brake line internally for a clean line from lever to caliper. The Colnago C64 carbon seatpost (the D-shaped design carried over from the V2-r aero platform) is also included. Both are purpose-designed components for this frame, and both would represent meaningful additional cost if purchased separately. The Colnago integrated headset is fitted and matched to the frame's carbon-elastomer cups. The fork is the C64 carbon disc fork, sized for 28mm tires with internal cable routing and a ribbed design developed for stiffness under hard braking. Built for Riders Who Know What They're Buying The Colnago C64 Disc frameset is for riders who've done the research and arrived at the same conclusion serious cyclists have reached for decades: that Colnago's lugged construction produces a road bike that rides unlike anything else at this price. The geometry — available in sloping sizes for aggressive positioning and high geometry sizes for a taller stack — covers a wide range of rider positions without requiring extreme spacer stacks. UAE Team Emirates races on Colnago. That's not marketing — it's the validation that comes from the world's best cyclists choosing a frame because it makes them faster, not because of a sponsorship deal that forces the choice. The C64 Disc carries that pedigree to the open market at a frameset price that makes it accessible to anyone serious enough to build around it properly.
