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.
MOMAG™
What is MoMag™?
A magnet and lots of ingenuity. This was what led to the patent for the well-tested “Mounting Magnet” system, or MoMag™.
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.
CUP & 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.
DIFFERENTIATED RIM HEIGHT
Two different heights for front and back. A bigger challenge in construction, but necessary to achieve the very best.
The lower front wheel improves handling, limiting weight to a maximum and also mass involved when turning and relaunching.
The rear rim is higher and more solid, to transmit all the power to the wheel and increase stability.
HIGH STRENGTH ALUMINUM
Special aluminium - the best aluminium wheels require carefully chosen materials. For "High strength Aluminum", Fulcrum® R&D uses only the best aluminium alloy 6082, with artificial ageing T6 temper that stabilises the alloy and gives it maximum life and reliability.
Aluminium 6082 has the highest strength of the 6000 series and has replaced 6061 in many applications. It is generally used for high-stress applications.
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.
