SPEED 40 DB

SPEED is synonymous with competition, and represents the ultimate in performance, above all when the stopwatch is the only means used to judge results on a racing bike. It the name of a product created for World Tour professionals, who use the tubular tyre version, and for all those who use these wheels for racing.

With the above as a premise, what features should the 40 mm-high, non-tubular SPEED wheel - which is ideal in most situations - have?

That's simple: the best of everything. And thus, the SPEED 40 DB, 2-Way Fit (tubeless) + disc brake wheel is born.
SPEED 40 DB is a set of wheels for use with disc brakes that will simply leave you speechless, featuring a cutting-edge rim with a new shape, designed according to innovative technical concepts. At 26.5 mm, the wheel is wider, with an aerodynamic shape which includes a pronounced 8 mm profile and a "twill" weave carbon fibre texture, optimising the elastic responsiveness of the rim.

The final aerodynamic profile is the fruit of a lengthy finishing process: from simulations to prototype testing, in order to select the best design whilst taking the side wind and the turbulence created by the disc into account, followed by a long analysis to choose the best materials to be used on the final product.

Need a few more hints to get a real feel for the spirit of this wheel? Here they are: the SPEED 40 DB boasts a 2-Way Fit construction - and as such is tubeless by conception - with a 19 mm wide channel, and a USB ceramic cone & cup bearing system. And, of course, the oversize flanges on the hubs are designed to take full advantage of all the benefits offered by the disc brake.

Ultimately, the SPEED 40 DB is the new point of reference for riders who have chosen to a disc brake, and who are looking for the very best wheels out there, with a true racing pedigree and a perfect mid-profile on the majority of routes.

SPEED 55 DB

The new rim profile characterizing the Speed 55 DB is a further step forwards in the search for the best aerodynamic performance. The model therefore focuses on a demanding and "racing" audience. To improve the rolling resistance (and ultimately the speed) of the wheel/tyre system, we designed this model in the 2-WAY FIT version.
The manufacturing process of the carbon fibre rim without holes in the internal channel - a patented construction technology - also allows a stronger and sturdier construction capable of withstanding even the most extreme racing conditions. The rim with a 19 mm inner width perfectly matches recent trends of using increasingly wider tyres - a choice that further improves the aerodynamic performance of the wheel/tyre system. This data has been validated by intensive wind tunnel studies and trials where new projects are tested on a regular basis. SPEED 55 DB proved to be the best option in terms of aerodynamic penetration indexes in the Fulcrum range and is derived from the profiles developed for the tubular version used by World Tour teams.
The SPEED range not only responds in terms of aerodynamic performance. Optimizing performance also requires the wheels to be light and run smooth. The scale stops at 1580 gr and we have chosen to add ceramic USB bearing components.
