Racing 4 DB Disc Hub

Technology

Disc Specific Rim

Fulcrum® is one of the first wheel manufacturers to offer two completely different rim profiles from disc to conventional brake. So, no adaptation, but a rim conceived based on years of design experience. As a brake track is not required, Fulcrum have designed a completely new profile, aimed at saving every single gram of weight and at improving aerodynamic efficiency. Its greater width makes it a perfect fit for tyres of 25/28mm upwards.

Asymmetric Rim

The asymmetry is designed to improve rim tension, balancing the forces from brakes and sprocket cassette.

Monoblock Hub for Disc

The rear hub of a top-quality disc brake wheel is a technical problem to be solved. Fulcrum®’s R&D department found itself facing a fundamental choice: on which side to put the oversize flange of the Two-to-one™ system? Disc or sprocket side? Without question – must stay on the sprocket side.
To combat the loss of braking power from flex and torque of the connector between the two sides of the hub, a special one-piece system has been devised with internal stiffening ribs.

AFS Axle System

The Axial Fixing System™ is the solution developed by Fulcrum® to fix the disc brake to the hub. The constraint granted by the butt area of the release mechanism, greater than in familiar standard ones, makes it possible to obtain greater structural rigidity and therefore more precise and powerful braking.

2 Way Fit Ready

This tubeless system is specifically designed for Fulcrum road wheels. Fulcrum recommend that the Schwalbe Tubeless easy (TL-Easy) tyre system is used. Please visit Fulcrum 2 Way-Fit Ready (Road) for further details.
