SPEED is synonymous with competition, it represents the maximum performance, when the stopwatch is the only judgment of a racing bike ride. It is a name created for World Tour professionals, who choose them in the tubular version, and for all those who use these wheels for racing.
With these premises, what characteristics should a SPEED version have, non-tubular, 40 mm high, and therefore ideal in multiple situations?
Simple: the best of everything. So SPEED 40 DB, 2-Way Fit (tubeless) + disc brake was born.
SPEED 40 DB is a jaw-dropping set of disc brake wheels, a cutting-edge 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 weave designed to optimize the elastic response of the rim.
It involved a long process of refining the aerodynamic profile: from simulations to tests with prototypes, to choose the best design taking into account the side wind and turbulence created by the disc, and a long test process to choose the best materials to join 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 & cup. And, obviously, the oversized hub flanges to take advantage of all the advantages that the disc brake brings with it.
Ultimately, SPEED 40 DB is the new point of reference for those who have chosen disc brakes and are looking for the best, with a competition pedigree and a medium profile perfect on most routes.
