Colnago G5-X
The G5-X is not just an evolution of the G4-X, it's Colnago's next-generation gravel bike. It's an entirely new platform, built from the ground up around how modern gravel riders actually ride and what they truly demand from their bikes.
Drawing on Colnago's deep expertise in performance cycling and their signature craftsmanship, the G5-X is constructed using their proven monocoque carbon frame construction. This keeps the weight of the bike down while maintaining a stiff, responsive ride. The result is a gravel bike designed to take you further. It combines the speed and efficiency to hold its own on the road with the capability to handle whatever lies beyond the pavement.
Colnago has increased the tire clearance to 53mm and it comes fitted with 50mm out of the box. To make sure you have everything you want along on your ride, they've also added in-frame downtube storage that can fit a tube, CO2 canister, tools, and a plug kit. Equipped with mounts on the top tube, downtube, and fork the G5-X is ready for however many racks or bags you may need on your journey. Whether it's loose gravel, rough doubletrack, or unpredictable terrain, the G5-X is primed and ready. If you're lining up for your local race, logging long days in the saddle, or carrying gear on a bikepacking trip, the G5-X adapts to the ride in front of you and is ready to go wherever your ride takes you.

GEOMETRY AND FIT
Compared to its predecessor, the G5-X has a longer wheelbase and longer chain stays. Paired with a slightly slacker head tube angle and longer reach, the bike is more stable and confident in descents.
NOT EXACTLY WHAT YOU’RE LOOKING FOR?
- Colnago C68 Gravel: More upright and comfort-oriented than the G5-X. Ideal for endurance rides.
- Colnago C68 Allroad: Similar to the C68 Road with spacing for tires up to 35mm, thanks to reinforced lower chainstays, providing the versatility to tackle road and gravel with equal confidence.
- Pinarello Dogma GR: Designed for endurance, exploration, and fun, with a smooth, responsive ride across everything from paved roads to off-road trails.
THE BOTTOM LINE
The Colnago G5-X is designed to meet the demands of modern gravel riding or racing. It is equipped with frame mounts and downtube storage to bring along whatever you may need during your race or bikepacking adventure. Its stable, yet efficient geometry gives every rider the confidence to pedal through even the most variable terrain. The G5-X truly stands out among modern gravel bikes.
The Colnago C68 is handcrafted in Cambiago, Italy, by the same hands that built bikes for cycling's greatest champions. At the heart of every C68 is Colnago's legendary modular construction, where individual carbon modules are precisely hand-assembled, then carbon-banded, filed, and polished to a seamless monocoque-like finish. The result is a frameset with exceptional structural integrity and flawless aesthetics.
The C68 Road Disc Frameset is the purist's race machine: full carbon construction with an oversized downtube and a bottom bracket for maximum power transfer. For riders who want something truly extraordinary, the C68 Titanium Road Disc Frameset takes that same platform and integrates 3D-printed titanium joints for a one-of-a-kind blend of materials, ride feel, and Italian artistry, with fully custom geometry available on request.
The C68 Allroad Disc Frameset opens up mixed-surface riding with 35mm tire clearance and a more comfortable, upright geometry, Colnago's racing DNA applied to everyday exploration. For riders who want to push further into gravel, the C68 Gravel Frameset steps it up with 42mm clearance, suspension fork compatibility, and a purpose-built geometry that keeps Colnago's snappy, responsive handling intact on demanding terrain.
The Colnago C72 is the latest evolution of the brand’s iconic C Series, combining high performance with traditional craftsmanship and modern design. Handmade in Italy using Colnago’s signature modular carbon construction, each frame is assembled and finished by hand, ensuring exceptional precision, quality, and durability.
This method produces a lightweight yet highly responsive frame, weighing just 895g unpainted, while preserving the smooth ride feel the series is known for. Through updates to the rear triangle and seat area, the C72 gets improved vibration absorption and overall ride compliance. And with tire clearance up to 35mm, it adapts well to variable conditions. Its revised geometry features a higher stack-to-reach ratio, creating a more balanced riding position that can support both aggressive efforts and endurance comfort.
Additional refinements include the CC.02 integrated cockpit, which reduces weight and improves aerodynamics while maintaining precise handling. A discreet integrated storage compartment adds practical functionality without affecting the bike’s clean design. Overall, the C72 delivers a refined, well-balanced ride experience that blends Colnago’s trusted heritage with advanced tech and performance capabilities.
The Colnago V5Rs is the pinnacle of modern racing bike engineering, purpose-built to compete at the highest level of WorldTour racing alongside elite riders like Tadej Pogačar. At just 685 grams ready-to-paint, it is the lightest frame Colnago has ever produced, achieving a remarkable 12.5% weight reduction over its predecessor without any compromise to structural integrity. This is made possible through advanced carbon fiber lamination techniques that precisely optimize every section of the frame for strength, durability, and minimal weight, setting a new benchmark for what a professional race bike can be. Beyond its featherlight construction, the Colnago V5Rs delivers aerodynamic performance that rivals dedicated aero road bikes. A redesigned frame geometry reduces frontal area by 13% compared to previous models, while a narrower, more refined head tube slices through the air with greater efficiency. The new lightweight fork enhances steering precision and supports tires up to 32mm, offering superior grip and confidence across a wide range of road surfaces. The V5Rs is not simply the lightest bike Colnago has ever made, it is the most complete race weapon in their storied lineup, engineered to win.
If you're looking for a more aero option check out the Y1Rs.
The Colnago Y1Rs is a high-performance aero road bike engineered for maximum speed, particularly for sprinters and breakaway riders. Its design prioritizes aerodynamic efficiency, stiffness, and low weight to deliver top performance in fast races. Developed in collaboration with WorldTour teams using Colnago’s “From-Race-to-Race” approach, the bike is the result of extensive data-driven design, including advanced CFD simulations and wind tunnel testing with academic partners.
A key innovation is its reduced frontal area—19% smaller than the V4Rs—achieved through a dual-plate construction that maintains stiffness while improving airflow. The integrated CC.Y1 cockpit enhances aerodynamics further with a V-shaped design that reduces drag and increases stiffness by 16% compared to competitors. Additional features like the DEFY Y-shaped seatpost joint and a tilted seat tube improve comfort and airflow under new UCI regulations.
Performance gains are significant: the Y1Rs requires 20 fewer watts than its predecessor to maintain 50 km/h and offers 3.5% greater stiffness in sprinting conditions. Its aggressive racing geometry, integrated components, and compatibility with wider tires make it ideal for elite riders focused purely on speed and efficiency.
