Fulcrum Speed 40 DB

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.
