Fulcrum SPEED 40 DB 28" wheel set, disc, carbon
The SPEED 40 DB boasts a 2-Way Fit construction with a 19mm wide channel and a USB ceramic cone and cup system. The oversized flanges on the hubs are designed to take full advantage of the disc brake.
SPEED is synonymous with the word race and represents maximum performance. Especially when the stopwatch is the only means of judging results on a racing bike. It's the name of a model created for World Tour pros who use the tube version and anyone who uses these wheels for racing.
Based on the above, what features should a 40mm high SPEED tubeless wheel have - which is ideal in most situations?
The SPEED 40 DB 2-Way Fit is a set of wheels for use with disc brakes that will not leave you alone, as it is equipped with a high-end rim with a new shape, designed according to innovative technical concepts. The 26.5mm wide rim has an aerodynamic shape that includes a distinctive 8mm profile and a "twill" carbon fiber weave structure that optimizes the rim's springy response.
The final aerodynamic profile is the result of a long finishing process: from simulations to prototype testing to select the best design while taking into account crosswinds and turbulence created by the disc, followed by a long analysis to select the best materials to be used in the final product.
Ultimately, the SPEED 40 DB is the new benchmark for disc brake riders who are looking for the best wheels with a true racing pedigree and a perfect center profile on most trails.
