Fulcrum has today launched its brand-new Speed 25 wheelset, designed to maximise climbing performance, and is celebrating the launch with a 10-day Strava challenge that offers a chance to win a set. They feature a 26mm profile, which is symmetrical on the front and asymmetrical on the back. According to Fulcrum, this optimises the sweet spot between lightness and aerodynamics, with the wheelset weighing a claimed 1,285g.

Developing the Speed 25 wheelset, according to Fulcrum, was inspired by its race-winning Racing Light XLR wheels, arguably some of the best lightweight wheels, which have proven popular with both the general public and the pros who favour them for mountain stages. Using this as a foundation on which to build, the brand has infused the new Speed 25 wheels with several of its proprietary technologies to maximise on lightness, handling and smoothness.
