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.
The asymmetry is designed to improve rim tension, balancing the forces from brakes and sprocket cassette.
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 an 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.
Fulcrum have redesigned the spokes and the hub housings to create a solid and unmoveable whole. Therefore, the spokes will never lose their initial tension, thus keeping the wheel perfectly reactive and centred, and these will remain in the position that have been studied during wind tunnel tests to ensure the best aerodynamic penetration possible.
Wide Rim Technologyy
Following request from the competition circuit, Fulcrum have created rims that are wider than before and thus providing the ideal basis for 25 / 28mm tyres of which have become much more common. This wide rim ensures stability, superior comfort and excellent handling.
Differentiated Rim Height
The lower front rim not only improves handling, but also reduces weight. The rear rim has a higher rim of which makes the wheel much more solid and responsive, and is better able to transmit power with increased stability.
