About Fulcrum Red Wind XLR 80mm Dark Clincher Rear Wheel – CULT
Red Wind XLR 80: what is truly impressive is their responsiveness and smoothness you’ll feel immediately on your road bike.
The most popular wheel depth among triathletes, with an impressive 80mm rim that push you faster towards the finish line.
The Red Wind XLR 80 mm. wheel is entirely hand-assembled by a specialized Fulcrum technician and it is checked in every tiny detail with electronic instrumentation.
And today Fulcrum® allows you to configure your Red Wind XLR 80 according to your preferences, in the Dark Label and Bright Label version.
Ceramic Ultimate Level Technology (CULT) – Behind this project is the exclusiveness of Cronitect® steel, using “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 using 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 on a daily basis 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 is 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.
A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag™.
Cup and Cone – The cup-and-cone bearing differs from the classic cartridge bearing because it works in perfect alignment with the forces involved, weight and thrust from the frame, as the bearings run in a race positioned directly opposing these forces.
Oversize Flange – The Oversize Flange was developed from the need to create a system to transmit every watt to the ground without dispersion, stiffening the wheel system where necessary, without having to add spokes or superstructures that increase weight.
The oversize flange uses physics to solve the problem. It increases dishing and enables spokes to be shortened. Doubling the spokes creates a balanced system that is excellent at transmitting torque.
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 when it comes to smoothness thanks to the use 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.
Aluminium 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.
The aluminum axle reduces the overall weight of the wheel.
Oversize Flange – Increases the torsional stiffness and reactivity at each change of the 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.
