Fulcrum Racing Speed Dark Carbon Clincher Wheelset

The new clincher version of Fulcrums venerable Racing Speed 40. Now you can train and race on the best. For those who want the optimal performance in all scenarios, The Speed 40C's 40mm rim profile is fast, and thanks to its 1420g weight, accelerates to speed like a climbing wheel. Experience carbon braking like never before with Fulcrum's 3Diament carbon braking surface, whereby the pads contact the carbon fibres directly.

Features:

• RDB™ Rim Dynamic Balance: The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.
• 2:1 Two-to-One™: When you push on the pedals, the rotational force on the sprocket induces a slackening of the freewheel spokes with a consequent loss of rim tension. This results in undesirable flex of the whole wheel and an unavoidable loss of energy. Fulcrum® has solved this classic cycling problem with its 2:1 Two-to-One™ Spoke Ratio patent, by doubling the spokes in the critical zones.
• DRSC™ - Directionated Rim-Spoke Coupling: Exclusive rim/spoke coupling system. It allows the rim, spokes, nipples and hub to align properly with the same tensioning value in all areas.
• Anti-Rotation System™: This new system raises the concept of spoking to a new level of performance for road bike and triathlon wheels. The Fulcrum® engineers have redesigned the spokes and the hub housings to create a solid and unmoveable whole. The result is that the spokes: a) will never lose their initial tension, thus keeping the wheel perfectly reactive and centred, b) will remain in the position that have been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.
• F.I.C. Fulcrum Identification Card - 100% Handmade Quality: Right from its inception Fulcrum® has been marked by feature that continues to this day: that is to design, prototype and industrialise all the wheels characterised by the red “F”. Indeed these take shape inside of the R&D, the leading-edge department that represents the beating heart of the Italian company. Every single component of the wheel, the materials chosen and the technologies applied are the tangible result of the effort that Fulcrum® makes every day to give you maximum performance and reliability.
• Traceability: A guarantee of quality. The keyword for our products is: traceable. If you find a little label attached to any Fulcrum® product, do not remove it. It will provide you a guarantee in case of an ascertained defectiveness of a production batch, and so the component needed or wheel will be traceable. All this because, devoted to its mission, Fulcrum® demands the absolute perfection and safety for its customers.
