Developed with a precise objective: maximum performance uphill.
Fulcrum’s new Speed 25 marry lightness and handling in a low profile wheel, which is perfect to conquer peaks and enjoy the downhills, thanks to the application of Fulcrum’s premier technologies.

The inspiration for the development of the Speed 25 were the race-winning Racing Light XLR. An extremely successful and popular wheel both with the general public and with the professional racers who used them for mountain stages. The Speed 25 have a 26 mm profile, which is symmetrical on the front and asymmetrical on the rear, to optimise the sweet spot between lightness and aerodynamics
With an official weight of only 1,285 grams, they are the ideal wheel for cyclists looking to post their best times uphill, but also for ultra-cyclists who have to deal with adverse weather conditions and want a stable and reliable wheel even in strong gusts of wind.

The Speed 25 have been developed in a disc-brake version, with an inner rim width of 21mm and Fulcrum’s proprietary technologies, MoMag™ and DIMF. The minimally-designed hubs use USB™ ceramic bearings. Lightness, handling and smoothness are the key aspects of the wheels’ performance.
