Fulcrum Speed 40T DB Disc CenterLock wheelset

Fulcrum Speed 40T DB Disc CenterLock wheelset

The Fulcrum Speed 40T DB Disc CenterLock are very light wheels for road racing. They are versatile, offer great aerodynamics and also do not penalize on slopes.

TIRE

The rim is made entirely of carbon fiber and is specific for disc brakes so it does not have a braking track. They have a 40mm aerodynamic profile.

It does not have holes in the outer wall, achieving a lighter wheel by not needing rim tape. No weakened areas where breaks can occur; This allows us to increase the tension of the spokes and achieve greater stiffness, reaction and acceleration, without reducing the duration of the rim or its resistance to fatigue.

It allows us to mount a wide range of tire sizes (25mm - 32mm).

RADIOS

Straight double-butted steel spokes with an aerodynamic profile, allowing maximum resistance to breakage and aerodynamic penetration.

The nipples are made of aluminum, which reduces the peripheral mass, increasing the reactivity of the wheel.

BUSHING

The hub body is made of carbon fiber and the flanges of aluminum.

It has adjustable CULT cone and bushing bearings with ceramic balls, which gives us great fluidity and ease of rotation.

The shaft is 17 mm and made of aluminum.

The core material is aluminum in both Shimano and Campagnolo.

TECHNOLOGIES

ANTI-ROTATION SYSTEM

The specific design of the hub and spokes creates a solid and immovable set. The result is that the spokes never lose their initial tension, and will also remain in the initial mounting position without turning.

DINAMIC BALANCE

Rim balancing resulting in a perfectly balanced rotational dynamics wheel.

2: 1 TWO-TO-ONE

Technology that doubles the spokes in critical areas to prevent loosening of the spokes when force is exerted on the pedals. As a result, there are two spokes that perform the function of one; loosening and twisting are limited and energy transfer is much more efficient. In addition, thanks to this system the tensions are more balanced, extending the life of the components.

DRSC - DIRECTIONATED RIM-SPOKE COUPLING

Fixing system of the spoke to the rim that reduces the unit load that supports each spoke, thus minimizing mechanical stress and prolonging the life of the wheel. In addition, it helps to maintain perfect balance and spoke tension in critical situations such as braking and acceleration.

MOMAG

It is a technology that allows the spoke head to be guided inside the rim magnetically, without the need to drill holes in the upper wall.

CULT CERAMIC ULTIMATE LEVEL TECHNOLOGY

A high quality cone, ceramic balls and a Cronitect steel bushing developed by FAG. The set provides a displacement fluidity up to 9 times higher than standard solutions. They make it possible to significantly reduce the coefficient of friction.

Rider weight limit: 109 Kg.
