The Speed 40C brings together materials and specifications to achieve "the pinnacle of wheel design", according to its manufacturer, which also calls it "a dream set of wheels for true bicycle lovers who will not settle for anything but the best."

SPEED 40C offers top performance in a wide variety of contexts: this versatile wheel was conceived as an ideal half-way solution with all the elements of a high-performance product, but with nothing omitted or compromised.

Designed for those seeking a winning set of wheels, SPEED 40C wheels are built with the same technology chosen for the World Tour but intended to be even more functional, thanks to the clincher tyre. The 40mm profile makes the most of aerodynamics and the flywheel effect, while remaining stable, easy to handle and quick on the climbs thanks to a balanced and reactive rim.

The Fulcrum SPEED 40C C17 Carbon Road Wheelset is the most versatile wheelset offered by Fulcrum. It features a 40mm rim profile that makes it perfect to cut through the air, yet it is stiff and easy to control in any weather conditions, while keeping weight to a minimum.

Perfect Tyre-to-Rim Interface

This wheelset is capable on any terrain. Featuring a 17mm internal rim width, it is perfectly suited to both 25 and 28c tyres. It has been designed to create the perfect tyre-to-rim interface with these modern tyre sizes, placing it firmly in the modern competitive race wheel category.

Stiff and Reactive

The Longitudinal Twill carbon rim design has been incorporated into these wheels. The fibres and the orientation in which they are structured pushes the boundaries of carbon fibre construction, resulting in a stiffer, more reactive rim that can also absorb higher levels of road vibration. You don't pay the price of a harsh ride for this ultimate level of performance and state-of-the-art materials ad construction techniques.

Exceptional Braking Performance

In addition to the technology that Fulcrum has developed to make this wheel go amazingly fast, it has also applied the AC3 braking surface to this model. This makes slowing down noticeably more responsive and powerful. This advanced coating on the braking surface provides exceptional braking performance and as a bonus, it also reduces rim wear.

  • Freewheel: Plasma Coated
  • Weight: 1.42kg

Technologies:

  • AC3 - All Conditions Carbon Control: AC3 enables surprising braking performance, which is very noticeable in difficult weather conditions. Rather than using the traditional machined brake track approach, Fulcrum uses micro laser incisions on the brake track surface to remove resins and create a smooth surface. Lab tests have shown that this process improves braking power by as much as 6%. However, in the wet this performance increase jumps to 43% - so your ability to brake in the wet comes closer to what can be achieved when riding in dry conditions.
  • USB (Ceramic Ultra Smooth Bearings): Using high-end ceramic balls, which perform continually thanks to the absence of lubricating grease and the precise machining of the cup and cone technology, friction is drastically reduced, and this in turn increases the smoothness of triathlon and road bike wheels by as much as nijne times compared to standard bearings.
  • Rim Dynamic Balance: Simple and elegant, the weight of the rim gasket is balanced on the opposite side with an item of similar weight.
  • 2:1 Two-To-One: Every push on your pedals will force most of that energy on the drive side of the rear wheel. To combat this loss of rim tension and power transfer, Fulcrum has solved this cycling problem with its 2:1 spoke ratio pattern, by doubling the spoke count in crucial zones on the wheel.
  • Directionalised Rim-Spoke Coupling: The exclusive rim/spoke mounting system allows the rim, spokes, hub and nipples to align perfectly, guaranteeing precise spoke tension all around the wheel.
  • Anti-Rotation System: This system locks the spoke in place once the correct tension is achieved. Engineers at Fulcrum have designed this system to ensure that the wheel's spokes never lose their initial tension and remain in the position that has been proven to provide the perfect aerodynamic properties.
  • Unrilled Rim Bed: Having no holes on the central section of the rim means that the rim is uniform at every point, and so is free from critical areas which might be subject to stress. The advantages are immediately clear: lower weight, longer-lasting rims, greater resistance to fatigue, and the possibility of giving the spokes more tension and more stiffness which, in terms of performance, means improved responsiveness and acceleration.
  • Plasma Freehub: The freehub body has been Plasma treated, which makes the aluminium especially hard and resistant to surface abrasion and wear. This means the thickness of materials used can be to be reduced to a minimum, achieving a lighter weight, while maintaining your wheel's lifespan and reliability.
