Fulcrum Wheels Speed 40 DB Disc

Fulcrum Wheels Speed 40 DB Disc Brake

SPEED is synonymous with competition, it represents maximum performance, when the stopwatch is the only judgment of a road bike ride. It is a name born for the professionals of the World Tour, who choose them in the tubular version, and for all those who use these wheels to race.

SPEED 40 DB is a jaw-dropping disc brake wheelset, a state-of-the-art rim, new in shapes and technical concepts. Wider, 26.5 mm, with an aerodynamic shape with a pronounced 8 mm nose and a "twill" carbon texture designed to optimize the elastic response of the rim.

It was a long work of refinement of the aerodynamic profile: from simulations to tests with prototypes, to choose the best design taking into account the lateral vento and turbulence created by the disc, and a long test work to choose the best materials to be combined in this project.

Other ideas to understand the soul of this wheel? Here they are: 2-Way Fit, therefore tubeless from birth, with a 19 mm wide channel.
Bearings: USB, ceramic, cone & shell. And, of course, the oversized flanges of the hubs to take advantage of all the advantages that the disc brake brings.
Ultimately, the SPEED 40 DB is the new benchmark for those who have chosen disc brakes and are looking for the best, with a racing pedigree and a perfect mid-profile on most routes.
