"A wheel with a lively character that is perfectly home when competition is the name of the game."

Racing1 wheels crown the Fulcrum range of aluminum wheels. They are wheels conceived for competition, but also ideal for everyday use. They feature an aggressive look, high technology, and light weight.

Racing1 wheels have a lively temperament for instant response in every competitive environment. Their aluminum rims, with a height of 26 mm, are lightened by the exclusive Fulcrum® triple milling system. There are no holes in the rim bed; this means that there is no need for rim tape and that the wheels are more torsionally rigid and vertically more elastic. The spokes 16 on the front wheel and 21 on the rear are forged in aluminum with a variable section and have a special aerodynamic design which broadens the spoke the nearer it is to the rim.

The result is improved aerodynamic penetration and a reduction in the formation or dangerous vortices.

The drive side of the rear wheel features Fulcrum's patented Two-to-One spoke lacing system. This means that the stresses are reduced while maintaining the same rear wheel rigidity and the life of the components increases.

Hubs are oversized with aluminium body and axle and with adjustable high-precision bearings.

Racing1 wheels feature perfectly balanced rotational dynamic thanks to the exclusive Fulcrum® Dynamic Balance™ technology.

Racing1 wheels are compatible with Campagnolo®, Shimano® and Sram® drivetrains.

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.

Unlike carbon rims, all the aluminum rims are joined. The joint, though indispensable, entails a concentration of material in a single point and creates an annoying “jump” effect at speed. Fulcrum® has eliminated this annoying problem with the Dynamic Balance™ patent.

The concept is simple and elegant: balance the mass of the joint with a mass of the same weight. For top models, this is obtained by a special operation on the section of the rim opposite the rim joint. For entry-level models, Dynamic Balance™ is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.

Though they have no holes in the rim bed, Racing3, Racing1 and RacingZero rims have spokes tensioned by traditional nipples. This makes tensioning and changing the spokes extraordinarily easy, and does away with questionable anchoring systems on the rim.

This solution was made possible thanks to the Fulcrum® MoMag™ patent which exploits magnetic power and a good dose of ingenuity to guide the nipples to the correct rim holes.
