Fulcrum Speed 25+ Carbon Tubeless Disc Brake Road Wheelset SRAM XDR 700c

Experience the pinnacle of road cycling performance with the Fulcrum Speed 25+ Carbon SRAM XDR Tubeless Disc Brake Road Wheelset. Engineered for precision and featherlight agility, these wheels redefine what’s possible in the realm of disc brake road cycling. With a sleek 700c design and cutting-edge carbon construction, the Speed 25+ offer an unparalleled combination of strength, low weight, and aerodynamic efficiency. Whether tackling steep alpine climbs or enduring long-distance rides, these wheels deliver a smooth, confident ride that only a low profile, high-quality carbon wheelset can provide.

At just 1270g, the Speed 25+ are the lightest low profile disc brake wheels ever produced by Fulcrum, incorporating advanced technologies that prioritize handling and durability without compromise. Featuring a thru-axle system compatible with 12 x 100mm front and 12 x 142mm rear setups, they ensure maximum stiffness and security. The asymmetric rim design enhances lateral stiffness and improves spoke tension balance, resulting in superior ride responsiveness and long-term reliability. With tubeless-ready compatibility, these wheels also offer the advantages of reduced rolling resistance and puncture protection, elevating your cycling experience.

Built with premium CULT™ ceramic bearings and an adjustable cup and cone bearing system, the hubs deliver smooth, long-lasting rotation, minimizing friction for enhanced speed and efficiency. The aero bladed, double-butted stainless steel spokes combine strength and aerodynamic advantage, while the full carbon rims (FF100) provide exceptional rigidity and impact resistance. With a rim width designed to accommodate tires from 25 to 65mm, these wheels are versatile enough to adapt to various road conditions and riding styles.

What It’s Good For

• Climbing steep alpine routes with ease thanks to ultralight construction
• Long-distance endurance rides requiring reliable and comfortable performance
• Riders seeking precise handling and responsive acceleration on disc brake road bikes
• Compatibility with both tubeless and traditional tube tires for versatile use
• Improved aerodynamic efficiency with a low profile 26mm rim depth
