Fulcrum Speed 55 Disc Road Wheelset

Ready for racing, this road bike wheelset features two high-quality full carbon rims that ensure maximum stiffness and strength without any weight penalty. Thanks to its carbon rim construction and carbon fibre finishing, this model makes climbing easier and when it’s time to descend, you won’t have to worry about any excess grams holding you back. Fulcrum has also equipped this version with many of its finest technologies, including 2-Way Fit so it can be used with or without tubeless tyres. With the ability to run lower tyre pressures, riders will enjoy performance benefits such as greater stability, increased comfort and fewer chances of flats or punctures as they race for the podium.

Wind Tunnel Tested Carbon Fibre Wheelset

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 19mm 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. 

Lightweight and Aerodynamic Performance

The Speed range not only responds in terms of aerodynamic performance. Optimising performance also requires the wheels to be light and run smooth. The Fulcrum Speed 55 Disc Road Wheelset weighs in at only 1580g and comes complete with ceramic USB bearings, so riders can enjoy smooth and dependable rolling performance as they race towards victory.
