Warning from the manufacturer:
Do not use carbon wheel red brake pads. This can lead to braking too much or to little in wet or dry conditions. Specific blue brake pads should be used.
A magnet and lots of ingenuity. This was what led to the patent for the well-tested " Mounting Magnet" system, or MoMag™. How does it work? The nipples, once inserted inside the rim via the valve hole, are " guided" to the point of connection with the spoke by means of the magnet. This simple but ingenious system makes it possible to have wheels without holes on the upper bridge, but with spokes tensioned by traditional nipples! The advantages: No holes on the rim means that the rim is uniform at every point, free from stress points or zones of weakness and, for the clincher profiles no rim tape is required, to the benefit of weight reduction. The advantages are immediately clear: greater rim lifetime, greater resistance to fatigue, the possibility to give the spokes greater tension, and greater stiffness which, in terms of performance, mean greater reactivity and acceleration. And not only that. The advantages make it extremely easy to work on and change spokes. Everything for the cyclist that chooses Fulcrum.
Fulcrum has a long-standing reputation for the extremely high performance of its hubs in terms of smoothness and reliability. In fact, all the projects are entirely developed in their R&D department and they have put obsessive care into taking care of every detail. The hubs with USB™ ceramic bearings (Ultra Smooth Bearings) further enhance the triathlon and road bike wheels' smoothness and reduce weight and the need for maintenance. Comparative tests have shown that USB™ bearings are 50 % smoother than standard bearings. Now improving your performance during the race or simply going for a ride with your friends will be easier.
Plasma Electrolytic Oxidation
The Plasma Electrolytic Oxidation treatment is a process made through electrical discharges that take advantage of heavy materials and free electrolytes. This process is an advanced oxidation process of light alloys of aluminium, magnesium and titanium. This special project was developed a few decades ago in the Russian laboratories to improve characteristics of the lightweight materials used in the space and military spaces. The Plasma Electrolytic Oxidation process gives the alloy surface very special characteristics regarding hardness and wear resistance.
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. As a result there are two spokes which carry out the function of one, slackening and torsion are limited and the transfer of the athlete's power is much more effective. Also, thanks to this system, spoke tensions are balanced more evenly between drive and non-drive sides and the fatigue life of the rim, hub and spokes is lengthened.
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.
