Road Frames

The V1-R may be the first monocoque frame in Colnago's stable that's light enough to hold its own with other top-end monocoque framesets. We weighed a 54cm frame with seat collar and headset at 1,080g, which puts it squarely on the average mark of the other Italian monocoque frames you'll see in the pro peloton. In fact, losing weight is something of a theme for the V1-R. It drops a claimed 150 grams compared to its predecessor, the Colnago M10. In addition to refined tube shaping and the world's best carbon fiber, small details like carbon rear dropouts and direct-mount brakes no doubt contribute by eliminating unnecessary hardware.

You know what 8 watts is? Victory. The new Dogma F12 supplies the aerodynamic advantage you need to stay ahead of the pack, with as much as 1 full second saved over a 1 kilometer course at 40 km/h. You'll produce more power and faster times thanks to pro-level performance enhancements, including a 10% increase in lateral stiffness in the frame and a 40% reduction in fork torque. Full internal cable routing decreases drag while creating a hyper-sleek aesthetic — disc models have no cables showing on the handlebar. The new design is not just about making the bike look good, but also combines geometrical, aerodynamic, and engineering advances to create Pinarello's latest world-class race machine.

Faster everywhere Our fastest lightweight road bike ever. The all-new SuperSix EVO destroys expectations. So light, so fast, and so aero, it defies logic. This is a machine built to make you faster everywhere. Speed has evolved. Where it thrives - Racing, the red zone, the pointy end, the podium What it's built for - Road racing, PRs, KOMs, winning Highlights - Superlight Hi-MOD carbon construction - incredibly light and responsive - Cannondale C1 Aero 40 Carbon Seatpost - light and fast The Lightest of the Fast Incredibly light. Thrillingly responsive. Blisteringly fast. Our advanced Hi-MOD carbon construction combines layers of high-strength fibers with precisely oriented layers of lightweight, high-stiffness fibers to deliver a frame that weighs just 810g, while surpassing all of our stiffness and fatigue tests. Pretty amazing for a bike this aerodynamic. The Fastest of the Light When it comes to aerodynamic drag, the new SuperSix EVO is not just one of the fastest lightweight road bikes out there, it's one of the fastest road bikes, period. When built up with our HollowGram 50 R-SL wheels and R-One SystemBar, its refined tube shapes and fully systemized design shave 12 watts off of our last generation model at 45 km/h, making it faster than many pure "aero" bikes while weighing up to a kilo less. Light or Aero? Now you don't have to choose.

The heart of a light and versatile expedition bike, and the endpoint of our Hook platform. This titanium version retains the vigor of our hooligan tourer and distills it into a light and comfortable frame. Able to accommodate multiple-wheel sizes, along with myriad luggage configurations, it’s ready to be the centerpiece in any number of different builds. Paired with our light yet staunch full-carbon EXT V2 fork, this provides triple cage mounts, along with steadfast handling in rough conditions.

The perfect escape vehicle. If it’s marked on the map, the Beyond can probably follow it. Sporting multiple frame and fork mounting points and mountain bike-width tire clearance, it’s a reliable companion for days, weeks, or months spent in the middle of nowhere.

A true mixte frame with the double top tube/stays. Obviously offers lots of standover height and style as well. You'll find the geometry is more sporty than upright-comfy. Though it can be built up to suit either demeanor. Drop bars? Sure. Townie bars? Of course. This version is updated for disc brakes. This not only improves wet weather braking but allows it to fit wider, more sure-footed tires. - Provides a great foundation for a premium townie or commuter with sport touring geometry - 650b conversions are possible and encouraged - Tange Prestige heat-treated butted CrMo steel - Tange sliding dropouts allow for geared or single-speed drivetrains - Rear hub spacing: 135mm QR with International Standard disc brake mounts - Clearance for 700x38c tires with fenders - Includes color-matched lugged fork - 5.0lbs (54cm)

It weighs in at 270 grams lighter than the C60.

Unparalleled speed, world-class aerodynamics, and Italian elegance combine to form Pinarello's Dogma F8 Frameset. The featherweight carbon construction, incredible power transfer, and ultra-responsive handling result in an otherworldly ride. From Pinarello's super high-end T1100 1K carbon, to the asymmetry of the chainstays, to the wind-cheating FlatBack tube shapes, everything on the Dogma F8 is crafted for aero speed. A seamlessly integrated tapered head tube housing Pinarello's voluptuous Onda F8 carbon fork provides laser-like steering control while reducing wind resistance and weight. And, the sleek, aerodynamic internal cable routing allows you to run either electronic or mechanical shifting systems, with interchangeable cable stops for Campagnolo, Shimano, or SRAM components.

DESIGN THE EXCEPTIONAL. We've always stood out from the crowd and created bikes that are totally unique, both in terms of how they look, but more importantly, how they perform. Form over function is a constant source of discussion between our head designers and we believe the DOGMA F achieves the perfect blend of the two. IMAGE FOR COLOR REFERENCE ONLY
