Fulcrum Racing 4 Wheelset Road 28" CA 9-12-speed Clincher black/red

Racing 4 promises a lot and gives even more: a wheel you can push to the limit Racing 4 is your secret weapon, no matter the challenge, it will always help you get more out of your ride.

It's light with a responsive medium profile offering an enviable superiority and eyes fixed on performance. You can see the similarities between the Racing 4 and our top-end wheels. The F E department has taken advantage of the experience gained in the development of pro-level rims to create a high-performance but affordable package.

The 35 mm profile strikes a successful balance between aesthetics and performance. Its medium-height rim profile makes a difference on the flats when riding at cruising speeds, without penalizing on the climbs, where it remains lively and agile during re-accelerations.

RDB Rim Dynamic Balance
The concept is simple yet ingenious: balance the mass of the rim joint with a mass of the same value, positioned exactly opposite.

Anti-rotation system
This new system brings the concept of the spoking system to a new level of performance.
Fulcrum engineers have redesigned the spokes and hub shells to create a strong and solid unit.
Here’s how this applies to the spokes:
a) that they never lose their initial tension and the wheel remains perfectly responsive and centered and
b) they remain in the position developed in the wind tunnel to ensure the best possible aerodynamics.

F.I.C. Fulcrum Identification Card - 100% Handmade Quality
Fulcrum, is characterized by an approach since its inception that continues to this day: Design, prototype development and industrialization of all wheels with the red "F".
Each wheel component, the selected materials and the technologies used are the tangible result of the efforts that the company Fulcrum spends every day to offer you the highest performance and reliability.

Wide Rim Tech
The Fulcrum F E department, following the requests of the racing teams, worked to create rims with a greater width in relation to the past, from about 4 mm more than the previous ones.
This technical choice makes it possible to offer the ideal support base for 25/28 mm tyres, the sizes preferred today. In this way, stability, optimum handling and high comfort are guaranteed.
