About Fulcrum Red Wind XLR 50mm Clincher Rear Wheel – CULT
Two-wheel enthusiasts were waiting for the Fulcrum “aluminium/carbon” wheels and the wait has been rewarded.
Indeed the Red Wind XLR represent the top-of-the-range road bike wheels in this segment thanks to their outstanding performance: the special aluminium/carbon structure combined with the oversize hub and spokes with the DRSC fastening system (Directional Rim-Spoke Coupling) give the wheel implausible responsiveness.
Ceramic Ultimate Level Technology (CULT) – Behind this project is the exclusiveness of Cronitect® steel, the use of “Advanced by FAG” technology by Schaeffler Group employed for the bearing races. This steel is resistent to the corrosion of the highest level until the point that no grease is necessary for lubrication, maybe just a small amount of oil.
The prime quality ceramic balls, thanks to the absence of lubricating grease and the precision machine of the cup and cone technology, allow to reduce the friction coefficient drastically and then increase the smoothness of triathlon and road bike wheels by as much as 9 times compared to standard bearings.
An outstanding result achieved by the use of state of the art technologies in the field of materials processing.
Rim Dynamic Balance (RDB) – 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.
Directionated Rim-Spoke Coupling (DRSC) – 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 conceivable.
Fulcrum Identification Card (FIC) – 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 each day to give you maximum performance and reliability.
Traceability – A guarantee of quality. The keyword for Fulcrum's products is: traceable. If you find a little label attached to any Fulcrum product, do not remove it. It’s going to 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.
Rim – Integrated aluminium/carbon rim structure: the exclusive coupling system of the aluminium rim and carbon structure makes these road bike rims extremely rigid, it allows for excellent responsiveness levels and durability of the wheel.
Exclusive pressing system for the rim in unpainted carbon enables an extremely limited weight and a smooth surface free from imperfections.
Hubs and Flanges – CULT ceramic bearings, the maximum on the subject of smoothness thanks to the usage of special reduced lubricant bearings.
The cone and cup technology with absolute performance: easy ball/bearing adjustment – reduces conceivable ball/bearing play – precision operation – maintains performance over time.
Aluminum hub body (gives the wheel a high degree of lateral stiffness and reduces weight to the minimum) with oversize aluminum flange and Two-to-One technology to transmit all the power to the ground. Aluminum axle reduces the overall weight of the wheel.
Oversize Flange – Increases the torsional stiffness, increasing reactivity at each change in rhythm of the pedal stroke.
Spokes and Nipples – Aerodynamic profile in steel ensures the maximum aerodynamic penetration and, thanks to the material employed, lower weight and greater reactivity.
Self-locking oversize aluminium nipples: they reduce the peripheral mass of the road bike wheels to a minimum, thus increasing responsiveness.
The nipples' self-locking system provides the correct tension of the spokes and does not require any maintenance.
