Official Fulcrum Racing 4 Center Lock Disc Wheelset – 2022 Model

The Racing 4 Center Lock Disc wheelset from Fulcrum is a versatile wheelset with 34 mm rim depth for your 28″ road bike. The medium-height rim design increases aerodynamics while maintaining steering precision. The anti-rotation system prevents the spoke tension from slackening, which means that even after many kilometres the wheels are just as stiff as they were at the start. The Square-Milling profile maintains stiffness and stability while keeping the weight low. Thanks to the 19 mm jaw width, you can easily mount tyres that are 25 or more millimetres wide. Not only are modern tyre sizes possible with this wheelset–thanks to the 2Way Fit system that is standard for Fulcrum, it is up to you whether you ride tubeless or resort to a tube.

Technology:

Anti Rotation System
Spokes and hubs are designed to form a solid unit. The initial tension of the spokes is permanently maintained. This keeps the wheel optimally trued.

Square Milling
A three-sided bevelled rim profile saves material, resulting in lower weight. In the area of the spoke holes, the rim is rectangularly reinforced, thus maintaining stability despite saving on material.
